Other functionality, such as video games, reference works, and social networking, can be enabled by downloading. As of January 2017, Apple's contained more than 2.2 million applications available for the iPhone. Apple has released eleven of iPhone models, each accompanied by one of the eleven major releases of the operating system. The original was a phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The added network support, and was followed by the with improved hardware, the with a metal chassis, higher display resolution and front-facing camera, and the with improved hardware and the voice assistant. The featured a taller, 4-inch display and Apple's newly introduced.

In 2013, Apple released the with improved hardware and a, and the lower-cost, a version of the 5 with colored plastic casings instead of metal. They were followed by the larger, with models featuring 4.7 and 5.5-inch displays. The was introduced the following year, which featured hardware upgrades and support for, as well as the —which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled the, which add water resistance, improved system and graphics performance, a new rear dual-camera setup on the Plus model, and new color options, while removing the 3.5 mm headphone jack found on previous models. The were released in 2017, adding a glass back and an improved screen and camera. The was released alongside the 8 and 8 Plus, with its highlights being a near bezel-less design, an improved camera and a new facial recognition system, named, but having no home button, and therefore, no.

The original iPhone was described as 'revolutionary' and a 'game-changer' for the mobile phone industry. Newer iterations have also garnered praise, and the iPhone's success has been credited with helping to make Apple one of the world's most valuable publicly traded companies. Coming soon On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six. Apple released the iPhone 3G in upwards of eighty countries and territories. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the US, Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost, and 40% of users had household incomes over US$100,000. The back of the original first generation iPhone was made of aluminum with a black plastic accent.

The iPhone 3G and 3GS feature a full plastic back to increase the strength of the signal. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. The iPhone 3GS was available in both colors, regardless of storage capacity. The iPhone 4 has an glass front and back with a edge that serves as the. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.

Users of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way. This became known as. On January 11, 2011, announced during a media event that it had reached an agreement with Apple and would begin selling a. Verizon said it would be available for pre-order on February 3, with a release set for February 10. In February 2011, the Verizon iPhone accounted for 4.5% of all iPhone in the US on Millennial Media's mobile ad network. From 2007 to 2011, Apple spent $647 million on advertising for the iPhone in the US. On Tuesday, September 27, Apple sent invitations for a press event to be held October 4, 2011, at 10:00 am at the Headquarters to announce details of the next generation iPhone, which turned out to be.

Over 1 million 4S models were sold in the first 24 hours after its release in October 2011. Due to large volumes of the iPhone being manufactured and its high selling price, Apple became the largest mobile handset vendor in the world by revenue, in 2011, surpassing long-time leader. American carrier announced that it would be carrying the iPhone 4S on October 19, 2011. In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an of nearly $660. The average selling price has remained fairly constant for most of the phone's lifespan, hovering between $622 and $660.

The production price of the iPhone 4S was estimated by, in October 2011, to be $188, $207 and $245, for the 16 GB, 32 GB and 64 GB models, respectively. Labor costs are estimated at between $12.50 and $30 per unit, with workers on the iPhone assembly line making $1.78 an hour. In February 2012, reported that 12.4% of US mobile subscribers used an iPhone.

Approximately 6.4 million iPhones are active in the US alone. On September 12, 2012, Apple announced the iPhone 5.

It has a 4-inch display, up from its predecessors' 3.5-inch screen. The device comes with the same 326 pixels per inch found in the iPhone 4 and 4S. The iPhone 5 has the A6 processor, the chip is 22% smaller than the iPhone 4S' A5 and is twice as fast, doubling the graphics performance of its predecessor. The device is 18% thinner than the iPhone 4S, measuring 7.6 millimetres (0.3 in), and is 20% lighter at 112 grams (4 oz).

On July 6, 2013, it was reported that Apple was in talks with Korean mobile carrier to release the next generation iPhone with LTE Advanced technology. On July 22, 2013, the company's suppliers said that Apple is testing out larger screens for the iPhone and iPad. 'Apple has asked for prototype smartphone screens larger than 4 inches and has also asked for screen designs for a new tablet device measuring slightly less than 13 inches diagonally, they said.' On September 10, 2013, Apple unveiled two new iPhone models during a highly anticipated press event in Cupertino. The iPhone 5C, a mid-range-priced version of the handset that is designed to increase accessibility due to its price is available in five colors (green, blue, yellow, pink, and white) and is made of plastic.

The iPhone 5S comes in three colors (black, white, and gold) and the home button is replaced with a fingerprint scanner (Touch ID). Both phones shipped on September 20, 2013. On September 9, 2014, Apple revealed the iPhone 6 and the iPhone 6 Plus at an event in Cupertino. Both devices had a larger screen than their predecessor, at 4.7 and 5.5 inches respectively. In 2016, Apple unveiled the, which add water and dust resistance, improved system and graphics performance, a new dual-camera setup on the Plus model, new color options, and remove the 3.5 mm headphone jack. On September 12, 2017, Apple officially unveiled the iPhone 8 and 8 Plus, which features a new glass design, camera improvements, a True Tone display, wireless charging and improved system performance. It also unveiled the iPhone X, which features a near-bezelless design, face recognition dubbed 'Face ID' with facial tracking used for Animojis, an OLED screen with the highest pixel density on an iPhone, a new telephoto lens which works better in low light conditions, and improved cameras for AR.

Sales and profits Apple sold 6.1 million first generation iPhone units over five quarters. Sales in the fourth quarter of 2008, temporarily surpassed those of 's (RIM) sales of 5.2 million units, which briefly made Apple the third largest mobile phone manufacturer by revenue, after and (However, some of this income is ). Recorded sales grew steadily thereafter, and by the end of 2010, a total of 73.5 million iPhones were sold. By 2010, the iPhone had a market share of barely 4% of all cellphones; however, Apple pulled in more than 50% of the total profit that global cellphone sales generate. Apple sold 14.1 million iPhones in the third quarter of 2010, representing a 91% unit growth over the year-ago quarter, which was well ahead of IDC's latest published estimate of 64% growth for the global smartphone market in the September quarter. Apple's sales surpassed that of 's 12.1 million units sold in their most recent quarter ended August 2010.

In the United States market alone for the third quarter of 2010, while there were 9.1 million Android-powered smartphones shipped for 43.6% of the market, Apple iOS was the number two phone operating system with 26.2% but the 5.5 million iPhones sold made it the most popular single device. On March 2, 2011, at the launch event, Apple announced that they had sold 100 million iPhones worldwide. As a result of the success of the iPhone sales volume and high selling price, headlined by the, Apple became the largest mobile handset vendor in the world by revenue in 2011, surpassing long-time leader. While the proved more popular than the iPhone 4S in parts of Europe, the iPhone 4S was dominant in the United States. In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an of nearly $660. The average selling price has remained fairly constant for most of the phone's lifespan, hovering between $622 and $660. For the eight largest phone manufacturers in Q1 2012, according to Horace Dediu at Asymco, Apple and Samsung combined to take 99% of industry profits (HTC took the remaining 1%, while RIM, LG, Sony Ericsson, Motorola, and Nokia all suffered losses), with Apple earning 73 cents out of every dollar earned by the phone makers.

As the industry profits grew from $5.3 billion in the first quarter of 2010 to $14.4 billion in the first quarter of 2012 (quadruple the profits in 2007), Apple had managed to increase its share of these profits. This is due to increasing carrier subsidies and the high selling prices of the iPhone, which had a negative effect on the wireless carriers (AT&T Mobility, Verizon, and Sprint) who have seen their EBITDA service margins drop as they sold an increasing number of iPhones.

By the quarter ended March 31, 2012, Apple's sales from the iPhone alone (at $22.7 billion) exceeded the total of from all of its businesses ($17.4 billion). In the fourth quarter of 2012, the and were the best-selling handsets with sales of 27.4 million (13% of smartphones worldwide) and 17.4 million units, respectively, with the in third with 15.4 million.

According to Strategy Analytics' data, this was 'an impressive performance, given the iPhone portfolio’s premium pricing,' adding that the Galaxy S III’s global popularity 'appears to have peaked' (the Galaxy S III was touted as an iPhone-killer by some in the press when it was released ). While Samsung has led in worldwide sales of smartphones, Apple's iPhone line has still managed to top Samsung's smartphone offerings in the United States, with 21.4% share and 37.8% in that market, respectively. IOS grew 3.5% to a 37.8%, while Android slid 1.3% to fall to a 52.3% share.

The continued top popularity of the iPhone despite growing Android competition was also attributed to Apple being able to deliver updates over the air, while updates are frequently impeded by carrier testing requirements and hardware tailoring, forcing consumers to purchase a new Android smartphone to get the latest version of that OS. However, by 2013, Apple's market share had fallen to 13.1%, due to the surging popularity of the Android offerings. Apple announced on September 1, 2013, that its iPhone trade-in program would be implemented at all of its 250 specialty stores in the US. For the program to become available, customers must have a valid contract and must purchase a new phone, rather than simply receive credit to be used at a later date.

A significant part of the program's goal is to increase the number of customers who purchase iPhones at Apple stores rather than carrier stores. On September 20, 2013, the sales date of the iPhone 5S and 5C models, the longest ever queue was observed at the New York City flagship Apple store, in addition to prominent queues in San Francisco, US and Canada; however, locations throughout the world were identified for the anticipation of corresponding consumers. Apple also increased production of the gold-colored iPhone 5S by an additional one-third due to the particularly strong demand that emerged.

Apple had decided to introduce a gold model after finding that gold was seen as a popular sign of a luxury product among customers. Apple released its opening weekend sales results for the 5C and 5S models, showing an all-time high for the product's sales figures, with 9 million handsets sold—the previous record was set in 2012, when 5 million handsets were sold during the opening weekend of the 5 model. This was the first time that Apple has simultaneously launched two models and the inclusion of China in the list of markets contributed to the record sales result. Apple also announced that, as of September 23, 2013, 200 million devices were running the iOS 7 update, making it the 'fastest software upgrade in history.'

An located at the in, US claimed the highest iPhones sales figures in November 2013. The store's high sales results are due to the absence of a in the state of. The finalization of a deal between Apple and China Mobile, the world's largest mobile network, was announced in late December 2013. The multi-year agreement provides iPhone access to over 760 million China Mobile subscribers.

In the first quarter of 2014, Apple reported that it had sold 51 million iPhones, an all-time quarterly record, compared to 47.8 million in the year-ago quarter. IPhone Upgrade Program The iPhone Upgrade Program is a 24-month program designed for consumers to be able to get the latest iPhone every year, without paying the whole price up-front. The program consists of 'low monthly payments', where consumers will gradually pay for the iPhone they have over a 24-month period, with an opportunity to switch (upgrade) to the new iPhone after 12 months of payment have passed. Once 12 months have passed, consumers can trade their current iPhone with a new one, and the payments are transferred from the old device to the new device, and the program 'restarts' with a new 24-month period. Additional features of the program include unlocked handsets, which means consumers are free to pick the network carrier they want, and 2-year AppleCare+ protection, which includes 'hardware repairs, software support, and coverage for up to two incidents of accidental damage'.

Criticism of the program includes the potential endless cycle of payments, with 's Damon Beres writing, 'Complete the full 24-month payment cycle, and you’re stuck with an outdated phone. Upgrade every 12 months, and you’ll never stop owing Apple money for iPhones'. Additionally, the program is limited to just the iPhone hardware; cell phone service from a network operator is not included. Legacy Before the release of the iPhone, handset manufacturers such as and were enjoying record sales of based more on fashion and brand rather than technological innovation. The smartphone market, dominated at the time by and devices, was a 'staid, corporate-led smartphone paradigm' focused on enterprise needs. Phones at the time were designed around carrier and business limits which were conservative with regards to bandwidth usage and battery life. Phones were sold in a very large number of models, often segmented by marketing strategy, confusing customers and sapping engineering resources.

For example, phones marketed at business were often deliberately stripped of cameras or the ability to play music and games. Apple's approach was to deliberately simplify its product line by offering just one model a year for all customers, while making it an expensive, high-end product. Apple's marketing, developing from the success of iPod campaigns, allowed the phone to become a mass-market product with many buyers on launch day.

Some market research has found that, unusually for a technology product, iPhone users are disproportionately female. Noted in 2012 that Apple had avoided 'patronizing' marketing to female customers, a practice used (often to sell low-quality, high-priced products) by many of its competitors. When then-CEO of pried open an iPhone, his impression was of a Mac stuffed into a cellphone, as it used much more memory and processing power than the smartphones on the market at the time. With its and consumer-friendly design, the iPhone fundamentally changed the mobile industry, with proclaiming in 2007, that the phone was not just a communication tool but a way of life.

The dominant mobile operating systems at the time such as,, and were not designed to handle additional tasks beyond communication and basic functions. These operating systems never focused on applications and developers, and due to infighting among manufacturers as well as the complexity of developing on their low-memory hardware, they never developed a thriving ecosystem like Apple's or 's. (renamed iOS in 2010) was designed as a robust OS with capabilities such as multitasking and graphics in order to meet future consumer demands. Many services were provided by mobile carriers, who often extensively customized devices.

Meanwhile, Apple's decision to base its OS on had the unexpected benefit of allowing OS X developers to rapidly expand into iOS development. Rival manufacturers have been forced to spend more on software and development costs to catch up to the iPhone. The iPhone's success has led to a decline in sales of high-end fashion phones and business-oriented smartphones such as and, as well as Nokia.

Nokia realised the limitations of its operating system Symbian and attempted to develop a more advanced system, Maemo, without success. It ultimately agreed to a technology-sharing deal and then a takeover from Microsoft. Prior to the iPhone, 'Handsets were viewed largely as cheap, disposable lures, massively subsidized to snare subscribers and lock them into using the carriers' proprietary services.' However, according to Wired, 'Apple retained complete control over the design, manufacturing, and marketing of the iPhone', meaning that it and not the carrier would control the software updates, and by extension security patches. By contrast, Google has allowed carriers and OEMs to dictate the 'pace of upgrades and pre-load phones with their own software on top of '. As a result, many Android OEMs often lag months behind Google's release of the next iteration of Android; although Nexus and Pixel devices are guaranteed 2 years of operating system updates and a third addition year for security. However, Apple has supported older iterations of iPhones for over 4 years.

In December 2017, there were reports that Apple has been using a policy of slowing down the speed of its older iPhones when issuing operating system upgrades. It has spurred allegations that the firm has been using this as a tactic to prompt users of older iPhones to buy newer models. Production Up to the, all iPhone models, as well as other were manufactured exclusively by, based in. In 2011, after became CEO of the company, Apple changed its outsourcing strategy, for the first time increasing its supply partners.

The in 2012 was the first model which was manufactured simultaneously by two stand-alone companies: Foxconn as well as, also based in Taiwan. Although Foxconn is still responsible for the larger share of production, Pegatron's orders have been slowly increased, with the company being tasked with producing a part of the line in 2013, and 30% of the devices in 2014. The 6 Plus model is being produced solely by Foxconn. Hardware Screen and input The on the first five generations is a 9 cm (3.5 in) with scratch-resistant glass, while the one on the is 4 inches. The is designed for a bare finger, or multiple fingers for sensing.

The screens on the first three generations have a resolution of 320×480 () at 163; those on the and have a resolution of 640×960 at 326 ppi; the 4-inch models, with 640×1136 at 326 ppi; the 4.7-inch models, with 750×1334 at 326 ppi; and the 5.5-inch models, with 1080×1920 at 401 ppi. The initial models were using. Starting with iPhone 4, the technology was changed to. The model's screen results in an aspect ratio of approximately 16:9. The is the first iPhone to use an display. It has a near bezel-less screen with a ~19.5:9 aspect ratio.

The touch and gesture features of the iPhone are based on technology originally developed. Most gloves and prevent the necessary electrical conductivity; although can be used with iPhone's finger-touch screen. The iPhone 3GS and later also feature a -resistant coating. The top and side of an iPhone 5S, externally identical to the iPhone 5.

From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The iPhone has a minimal hardware user interface, featuring five.

The only physical menu button is situated directly below the display, and is called the 'Home button' because it closes the active app and navigates to the home screen of the interface. The home button is denoted not by a house, as on many other similar devices, but a, reminiscent of the shape of icons on the home screen. However, the Home button on iPhones with Apple's feature (which use the Home button as the fingerprint sensor) have no symbol. The doesn't have a Home button but instead, a facial recognition authentication method. A multi-function sleep/wake button is located on the top of the device. It serves as the unit's power button, and also controls. When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voicemail.

Situated on the left spine are the volume adjustment controls. The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch, which could reasonably be counted as either one or two buttons. Directly above the volume controls is a ring/silent switch that when engaged mutes telephone ringing, alert sounds from new & sent emails, text messages, and other push notifications, camera shutter sounds, Voice Memo sound effects, phone lock/unlock sounds, keyboard clicks, and spoken auto-corrections. This switch does not mute alarm sounds from the Clock application, and in some countries or regions it will not mute the camera shutter or Voice Memo sound effects. All buttons except Home were made of plastic on the original first generation iPhone and metal on all later models. The touchscreen furnishes the remainder of the. A software update in January 2008 allowed the first-generation iPhone to use cell tower and Wi-Fi network locations, despite lacking hardware.

Since the iPhone 3G generation, the iPhone employs operated by the United States. Since the iPhone 4S generation the device also supports the global positioning system, which is operated by Russia. The iPhone 6S and 6S Plus, introduced in 2015, feature ' displays which allows the screen to recognize how hard it is being pressed. An example of how this technology will be used is lightly pressing the screen to preview a photograph and pressing down to take it.

Proximity sensor A deactivates the display and when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears. Ambient light sensor An adjusts the display brightness which saves battery power and prevents the screen from being too bright or too dark. Accelerometer A 3-axis senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between mode.

Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations. Unlike the, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input. The accelerometer can also be used to control, notably games. It is also used for fitness tracking purposes, primarily as a. Magnetometer A is built-in since the iPhone 3GS, which is used to measure the strength and direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure 8 motion.

Since the iPhone 3GS, the iPhone also features a Compass app which was unique at time of release, showing a compass that points in the direction of the magnetic field. Gyroscopic sensor Beginning with the iPhone 4, Apple's smartphones also include a, enhancing its perception of how it is moved. Radio Previous iPhone models contained a chip capable of receiving; however, Apple has the FM radio feature switched off because there was no antenna connected to the chip.

Later iterations of the iPhone (starting with the iPhone 7), however, does not contain radio chips at all. A campaign called 'Free Radio On My Phone' was started to encourage cellphone manufacturers such as Apple to enable the radio on the phones they manufacture, reasons cited were that radio drains less power and is useful in an emergency such as the. Fingerprint sensor All iPhone models starting from (excluding the and ) feature Apple's sensor.

It is used for unlocking the device and authenticating purchases (since the ) using. It is located in the home button.

Barometer Included on the and later (excluding the ), a used to determine air pressure, and elevation from the device. Facial recognition sensor The features a sensor, named the TrueDepth camera system. It is used for unlocking the device and for authenticating purchases using. It can also be used for and. Audio and output. From left to right is the headphone jack, microphone, Lightning connector, and built-in speaker on the base of the iPhone 5S.

On the bottom of the iPhone, there is a speaker to the left of the dock connector and a microphone to the right. There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone 4 includes an additional at the top of the unit for, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the right. Volume controls are located on the left side of all iPhone models and as a slider in the iPod application. The 3.5mm for the headphones is located on the top left corner of the device for the first five generations (original through 4S), after which time it was moved to the bottom left corner. The headphone socket on the 1st-generation iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter. Subsequent generations eliminated the problem by using a flush-mounted headphone socket.

Cars equipped with an allow handsfree use of the iPhone while driving as a substitute for. The iPhone 7 and later have no 3.5mm headphone jack, and instead headsets must connect to the iPhone by, use Apple's (which has replaced the 3.5mm headphone jack), or (for traditional headsets) use the Lightning to 3.5mm headphone jack adapter, which is included with all iPhone 7 and later units, and plugs into the Lightning port. Apple's own has a multipurpose button near the microphone that can play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. Some third-party headsets designed for the iPhone also include the microphone and control button.

The current headsets also provide volume controls, which are only compatible with more recent models. A fourth ring in the audio jack carries this extra information. The built-in supports wireless earpieces and headphones, which requires the. Stereo audio was added in the 3.0 update for hardware that supports. While non-sanctioned third-party solutions exist, the iPhone does not officially support the. The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other Bluetooth-enabled cell phones. Composite or component video at up to and stereo audio can be output from the dock connector using an adapter sold by Apple.

IPhone 4 also supports 1024×768 output without audio, and output, with stereo audio, via dock adapters. The iPhone did not support until the 3.0 software update.

Replacing the battery requires disassembling the iPhone unit and exposing the internal hardware The iPhone features an internal rechargeable. Like an iPod, but unlike most other mobile phones at the time of its launch, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to. Alternatively, a USB to AC adapter (or 'wall charger,' also included) can be connected to the cable to charge directly from an. Apple runs tests on preproduction units to determine battery life.

Apple's website says that the battery life 'is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles', which is comparable to iPod batteries. The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims.

This is also reflected by a customer satisfaction survey, which gave the 'battery aspects' of the iPhone 3G its lowest rating of 2 out of 5 stars. If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under. The warranty lasts one year from purchase and can be extended to two years with. The battery replacement service and its pricing was not made known to buyers until the day the product was launched; it is similar to how Apple (and third parties) replace batteries for iPods. The, a group, has sent a complaint to Apple and over the fee that consumers have to pay to have the battery replaced. Since July 2007, third-party battery replacement kits have been available at a much lower price than Apple's own battery replacement program.

These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the first generation iPhone has been in. Therefore, a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace.

The iPhone X features a different battery, with two battery cells, and the adhesive pull tabs are adhered to the sides instead of folded over the top, therefore making repairs a little more difficult than before. A patent filed by the corporation, published in late July 2013, revealed the development of a new iPhone battery system that uses location data in combination with data on the user's habits to moderate the handsets power settings accordingly. Apple is working towards a power management system that will provide features such as the ability to estimate the length of time a user will be away from a power source to modify energy usage and a detection function that adjusts the charging rate to best suit the type of power source that is being used.

(December 2017) () The 1st-generation iPhone and iPhone 3G have a 2.0- camera on the back for digital photos. It has no optical zoom, flash or, and does not natively support video recording.

(iPhone (original) & 3G can record video via a third-party app available on the App Store, and also allows users to do so.) IPhone OS 2.0 introduced for photos. The iPhone 3GS has a 3.2-megapixel camera with autofocus, auto white balance, and auto macro (up to 10 cm). Manufactured by, the camera can also capture 640×480 ( resolution) video at 30 frames per second. The video can be on the iPhone and directly uploaded to YouTube or other services. The iPhone 4 introduced a 5.0- camera (2592×1936 pixels) that can record video at resolution, considered. It also has a sensor that can capture pictures in low light and an that can stay lit while recording video. It is the first iPhone that can natively do.

The iPhone 4 also has a second camera on the front that can take photos and record video. Saved recordings may be synced to the host computer, attached to email, or (where supported) sent.

The iPhone 4S' camera can shoot 8-MP stills and 1080p video, can be accessed directly from the lock screen, and can be triggered using the volume-up button as a shutter trigger. The built-in gyroscope can stabilize the image while recording video. The and, running or later, can take panoramas using the built-in camera app, and the can also take still photos while recording video.

The camera on the reportedly shows purple haze when the light source is just out of frame, although Consumer Reports said it 'is no more prone to purple hazing on photos shot into a bright light source than its predecessor or than several Android phones with fine cameras.' On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice. On all iPhones running, it can also be accessed from the lock screen directly. The iPhone 5S features True Tone Flash, which has two LED lights, white and amber, that will improve white balance and will be adjusted in 1,000 combinations. The iPhone 6 and 6 Plus included, while the 6 Plus has. Both models can now shoot 1080p videos at 60 frames per second.

The iPhone 6S and 6S Plus are outfitted with a 12 megapixel camera, with 4K HD video capability. It also updated its front camera to 5 megapixels, which is good for capturing self-portraits. The user may change the resolution between 4K and 1080p from Settings. The iPhone 7 features OIS on its rear camera, a feature that was previously exclusive to the Plus models, and the 7 Plus is the first iPhone to feature dual-lens cameras (both 12 MP), and they both have a 7 MP front-facing camera. The second camera on the iPhone 7 Plus is a, which enables 2x optical zoom and up to 10x digital zoom. The rear cameras on the 7 and 7 Plus both have a f/1.8. It also has a new quad-LED True Tone flash, which is brighter compared to its predecessors.

The iPhone 8 camera remains largely the same as its predecessor, but it features a larger sensor, and a newer color filter. The camera can also now record at 60 and 24 frames per second, and at in 240 frames per second. The new camera system also enables Portrait Lighting, which defines the light in a scene. It also features a quad-LED True Tone flash, but it now has 2× better light uniformity and Slow Sync.

The iPhone X camera is almost the same as the iPhone 8's camera, but the lens now has an of f/2.4 and optical image stabilization. The front camera also has Portrait Mode and Portrait Lighting, due to the new TrueDepth camera system. This section needs additional citations for. Unsourced material may be challenged and removed. (December 2017) () The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB.

On September 5, 2007, Apple discontinued the 4 GB models. On February 5, 2008, Apple added a 16 GB model. The iPhone 3G was available in 16 GB and 8 GB.

The iPhone 3GS came in 16 GB and 32 GB variants and remained available in 8 GB until September 2012, more than three years after its launch. The iPhone 4 was available in 16 GB and 32 GB variants, as well as an 8 GB variant to be sold alongside the iPhone 4S at a reduced price point. The iPhone 4S was available in three sizes: 16 GB, 32 GB and 64 GB. The iPhone 5 and 5S were available in the same three sizes previously available to the iPhone 4S: 16 GB, 32 GB, and 64 GB. The lower-cost iPhone 5C model was initially available in 16 GB and 32 GB models; an 8 GB model was added later.

The iPhone 6 and 6S are available in three sizes: 16 GB, 64 GB, and 128 GB. The iPhone SE is available in 16 GB and 64 GB variants. By the time the iPhone 7 and 7 Plus was released, Apple ditched the based model from 16 GB to 32 GB as the base storage. Both 7 & 7 Plus has a configuration of 32, 128, & 256 GB storage option. And Apple also doubled the storage on the iPhone 6S & 6S Plus in 2 configurations (32 GB & 128 GB), as well as the iPhone SE six months later. An iPhone 5S with the SIM slot open.

The SIM ejector tool is still placed in the eject hole. Models of the iPhone use a to identify themselves to the GSM network. The SIM sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with a or the 'SIM ejector tool' (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS in the United States and with all models elsewhere in the world. Some iPhone models shipped with a SIM ejector tool which was fabricated from an alloy dubbed '. In most countries, the iPhone is usually sold with a, which prevents the iPhone from being used on a different mobile network. The iPhone 4 features a card that is located in a slot on the right side of the device.

The model of the iPhone 4, just the same as any other CDMA-only cell phone, does not use a SIM card or have a SIM card slot. An iPhone 4S activated on a CDMA carrier, however, does have a SIM card slot but does not rely on a SIM card for activation on that CDMA network. A CDMA-activated iPhone 4S usually has a carrier-approved roaming SIM preloaded in its SIM slot at the time of purchase that is used for roaming on certain carrier-approved international GSM networks only. The SIM slot is locked to only use the roaming SIM card provided by the CDMA carrier.

In the case of Verizon, for example, one can request that the SIM slot be unlocked for international use by calling their support number and requesting an international unlock if their account has been in good standing for the past 60 days. This method only unlocks the iPhone 4S for use on international carriers. An iPhone 4S that has been unlocked in this way will reject any non international SIM cards (AT&T Mobility or T-Mobile USA, for example). The iPhone 5 and later iPhones use the, in order to save more space for internal components. Liquid contact indicators All iPhones (as well as many other devices by Apple) have a small disc at the bottom of the headphone that changes from white to red on contact with water; the iPhone 3G and later models also have a similar indicator at the bottom of the. Because Apple warranties do not cover water damage, employees examine the indicators before approving.

The iPhone's indicators are more exposed than those in some mobile phones from other manufacturers, which carry them in a more protected location, such as beneath the battery behind a battery cover. These indicators can be triggered during routine use, by an owner's sweat, steam in a bathroom, and other light environmental moisture.

Criticism led Apple to change its water damage policy for iPhones and similar products, allowing customers to request further internal inspection of the phone to verify if internal liquid damage sensors were triggered. Included items. The contents of the box of an iPhone 4. From left to right: iPhone 4 in plastic holder, written documentation, and (top to bottom) headset, USB cable, wall charger. All include written documentation, and a to cable. The first generation and 3G iPhones also came with a cleaning cloth.

The first generation iPhone included a stereo ( and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhone includes a similar headset plus a SIM eject tool (the first generation model requires a ). The iPhone includes the eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions). The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the first generation model's dock. All versions include a USB power adapter, or 'wall charger,' which allows the iPhone to charge from an. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, and Peru include an ultracompact USB power adapter.

Main articles: and The iPhone runs an known as (formerly iPhone OS). It is a variant of the same operating system core that is found in Mac. Also included is the ' software component from Leopard. Together with the hardware (and on the iPhone 3GS, 2.0), it is responsible for the interface's. The iPhone comes with a set of bundled applications developed by Apple, and supports downloading third-party applications through the. Apple provides free updates to the operating system for the iPhone either wirelessly or through iTunes. Major new updates have historically accompanied new models.

The size of the operating system depends on version. While required over 4.5 GB, required only 1.3 GB. Interface The is based around the home screen, a graphical list of available applications. IPhone applications normally run one at a time. Starting with the iPhone 4, a primitive version of multitasking came into play. Users could double click the home button to select recently opened applications.

However, the apps never ran in the background. Starting with iOS 7, though, apps can truly multitask, and each open application runs in the background when not in use, although most functionality is still available when making a call or listening to music. The home screen can be accessed at any time by a hardware button below the screen, closing the open application in the process. By default, the Home screen contains the following icons: Messages ( and messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (), Weather, Voice Memos, Notes, Clock, Calculator, Settings,,, (on the iPhone 3GS and iPhone 4), FaceTime and GameCenter were added in iOS 4.0 and 4.1 respectively. In iOS 5, Reminders and Newsstand were added, as well as the iPod application split into separate Music and Videos applications. IOS 6 added Passbook as well as an updated version of Maps that relies on data provided by TomTom as well as other sources.

IOS 6 also added a Clock application onto the iPad's homescreen. YouTube no longer came as a pre-installed application. Docked at the base of the screen, four icons for,, (Internet), and Music delineate the iPhone's main purposes. On January 15, 2008, Apple released software update 1.1.3, allowing users to create 'Web Clips', home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons (by holding down on any icon and moving it to the desired location once they start shaking) on up to nine other adjacent home screens, accessed by a horizontal swipe. Users can also add and delete icons from the dock, which is the same on every home screen. Each home screen holds up to twenty icons for the,, and, while each home screen for holds up to twenty-four icons due to a larger screen display, and the dock holds up to four icons.

Users can delete Web Clips and third-party applications at any time, and may select only certain applications for transfer from iTunes. Apple's default programs, could only be removed since the iOS 10 update. The 3.0 update adds a system-wide search, known as, to the left of the first home screen. Almost all input is given through the touch screen, which understands complex gestures using.

The iPhone's enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as '.

Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction.

In this way, the interface of a real object. Unlike previous scrollable views, in which the user pressed a 'down' control to move the view 'downwards', on iOS the user pushes upwards, as if moving a 'plank of wood floating on the water', creating the impression that the user is directly manipulating the content displayed on the screen. Other effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side.

Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a 'back' button in the top-left corner of the screen displays the name of the parent folder. When making a call, the iPhone presents a number of options, including on supported models. The screen is when held close to the face. The iPhone allows audio, call holding, call merging,, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out, and fades back in when the call has ended.

The shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone does not support or on versions prior to the fourth generation, as there is only one camera on the opposite side of the screen. The iPhone 4 supports video calling using either the front or back camera over Wi-Fi, a feature Apple calls. Voice control, introduced in the iPhone 3GS, allows users to say a contact's name or number and the iPhone will dial it. The first two models only support through third-party applications. The iPhone includes a (in some countries) feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list.

A music feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped,. All customizing can be done in iTunes, or with Apple's software 4.1.1 or later (available only on ) or third-party tools. With the release of, which was released on September 19, 2012, Apple added features that enable the user to have options to decline a phone call when a person is calling them. The user can reply with a message, or to set a reminder to call them back at a later time. Multimedia The layout of the music library is similar to that of an or current phones.

The iPhone can sort its media library by songs, artists, albums, videos,,, composers,,, and. Options are always presented alphabetically, except in playlists, which retain their order from. The iPhone uses a large font that allows users plenty of room to touch their selection. Users can rotate their device horizontally to to access.

Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks.

On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create a. The iPhone supports. Like the introduced in 2005, the iPhone can play, allowing users to watch TV shows and movies in. Double-tapping switches between widescreen and video playback. The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but now since 2012, can use the cellular data network if one is not available.

The iPhone includes software that allows the user to upload, view, and email photos taken with the. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. Those pictures are also available in the Photos application, along with any transferred from or on a Mac, or on a Windows PC. Internet connectivity. The on the first generation iPhone For text input, the iPhone implements a on the touchscreen.

It has automatic and correction, capabilities, and a dynamic dictionary that learns new words. The keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys near the presumed desired key. The keys are somewhat larger and spaced farther apart when in, which is supported by only a limited number of applications. Touching a section of text for a brief time brings up a, allowing users to place the in the middle of existing text. The virtual keyboard can accommodate 21 languages, including character recognition for Chinese.

Alternative characters with accents (for example, letters from the alphabets of other languages) and can be typed from the keyboard by pressing the letter for 2 seconds and selecting the alternative character from the popup. The 3.0 update brought support for text, as well as landscape keyboards in more applications. On iPhone 4S and above, Siri allows dictation. Email and text messages The iPhone also features an email program that supports, which enables the user to embed photos in an email message.,,, and attachments to mail messages can be viewed on the phone.

Offers a free push-email service for the iPhone. (although not ) and mail standards are also supported, including and. In the first versions of the iPhone firmware, this was accomplished by opening up IMAP on the Exchange server. Apple has also licensed and supports the platform (including push email) with the release of iPhone 2.0 firmware. The iPhone will sync email account settings over from Apple's own application,, and, or it can be manually configured on the device itself. The email program can access almost any IMAP or POP3 account.

Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar to ) under each recipient's name. The iPhone has built-in support for email message forwarding, drafts, and direct internal camera-to-email picture sending. Support for multi-recipient SMS was added in the 1.1.3 software update. Support for was added in the 3.0 update, but not for the original first generation iPhone and not in the US until September 25, 2009.

Third-party applications. See also: and At on June 11, 2007, Apple announced that the iPhone would support web applications using that share the look and feel of the iPhone interface. On October 17, 2007, Steve Jobs, in an open letter posted to Apple's 'Hot News', announced that a (SDK) would be made available to third-party developers in February 2008. The iPhone SDK was officially announced and released on March 6, 2008, at the Apple Town Hall facility. It is a free download, with an Apple registration, that allows developers to develop native applications for the iPhone and iPod Touch, then test them in an 'iPhone simulator'. However, loading an application onto a real device is only possible after paying an membership fee. Developers are free to set any price for their applications to be distributed through the, of which they will receive a 70% share.

Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the membership fee. The App Store was launched with the release of iOS 2.0, on July 11, 2008. The update was free for iPhone users; owners of older iPod Touches were required to pay US$10 for it. Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. Apple can halt the distribution of applications it deems inappropriate, for example,, a US$1000 program that simply demonstrated the wealth of its user. Apple has been criticized for banning third-party applications that enable a functionality that Apple does not want the iPhone to have: In 2008, Apple rejected, which allowed iPhone users to download podcasts directly to the iPhone claiming it duplicated the functionality of iTunes.

Apple has since released a software update that grants this capability. NetShare, another rejected app, would have enabled users to their iPhone to a laptop or desktop, using its cellular network to load data for the computer. Many carriers of the iPhone later globally allowed tethering before Apple officially supported it with the upgrade to the iOS 3.0, with being a relative latecomer in the United States.

In most cases, the carrier charges extra for tethering an iPhone. Before the SDK was released, third parties were permitted to design 'Web Apps' that would run through Safari. Unsigned native applications are also available for 'jailbroken' phones. The ability to install native applications onto the iPhone outside of the App Store is not supported by Apple, the stated reason being that such native applications could be broken by any software update, but Apple has stated it will not design software updates specifically to break native applications other than those that perform SIM unlocking.

As of October 2013, Apple has passed 60 billion app downloads. As of September 2016, there have been over 140 billion app downloads from the App Store. As of January 2017, the App Store has over 2.2 million apps for the iPhone. Reception The original iPhone has been described as 'revolutionary', a 'game-changer' for the mobile phone industry, and has been credited with helping to make Apple one of the world's most valuable publicly traded companies by 2011. Newer iterations have also received praise, such as being called 'the best phone'. The iPhone attracts users of all ages, and besides consumer use, the iPhone has also been adopted for. Accessibility features Starting with the iPhone 4S, Apple added an feature to optimize the function of the iPhone with.

Apple released a program of Made for iPhone Hearing Aids. These hearing aids deliver a power-efficient, high-quality digital audio experience and allow the user to manage the hearing aid right from your iPhone. Made for iPhone hearing aids also feature. With Live Listen the iPhone acts as a remote that sends sound to a Made for iPhone hearing aid. Live Listen can help the user hear a conversation in a noisy room or hear someone speaking across the room. The for iOS program was announced by Apple coinciding with the release of the iPhone 3GS, and. This program added support for more than 50 Bluetooth wireless braille displays that work with iOS out of the box.

The user only needs to pair the keyboard to the device to start using it to navigate the iOS device with without any additional software. IOS supports for more than 25 languages. IPhone lets the user know when an alert is sent to the it, in a variety of notice methods. It delivers both and for incoming phone and calls, new text messages, new and sent mail, and calendar events. You can set an for incoming calls and alerts. Or have incoming calls display a photo of the caller.

Users can choose from different vibration patterns or even create their own. The iPhone can enlarge text to make it more for vision-impaired users, and can accommodate hearing-impaired users with and external devices. The iPhone 3GS also features white on black mode, (a ), and zooming for impaired vision, and mono audio for in one ear. Apple regularly publishes Voluntary Product Accessibility Templates which explicitly state compliance with the US regulation '. With the release of the newer iOS 9 for all iPhones, users now have the ability to choose between 2 different screen view options.

The user can choose to have a standard view or zoomed view. When the iPhone is placed in a standard view setting, the icons are normal size and the text remains the same. With a zoomed view option, the icons on the screen and the text become slightly larger. This enables the user to have a more customized appearance and it can potentially help some users read the screen easier. AssistiveTouch helps to adapt the screen of an iOS device to your unique physical needs.

This can be of great assistance to those who have difficulty with some gestures, like pinch, one can make them accessible with just a tap of a finger. The user can create their own gestures and customize the layout of the AssistiveTouch menu. If the user has trouble pressing the Home button, it can be set so that it can be activated with an onscreen tap.

Gestures like rotate and shake are available even when if the iOS device is mounted on a. Guided Access helps people with or other and stay focused on the task (or app) at hand. With Guided Access, a parent, teacher, or therapist can limit an iOS device to stay on one app by disabling the Home button, and limit the amount of time spent in an app.

The user can even restrict access to the keyboard or touch input on certain areas of the screen. So wandering taps and gestures won’t distract from learning. Sources: press release library Intellectual property Apple has filed more than 200 related to the technology behind the iPhone.

LG Electronics claimed the design of the iPhone was copied from the. Woo-Young Kwak, head of LG Mobile Handset R&D Center, said at a press conference: 'we consider that Apple copied Prada phone after the design was unveiled when it was presented in the iF Design Award and won the prize in September 2006.' On September 3, 1993, filed for the US trademark 'I PHONE' and on March 20, 1996, applied for the trademark 'IPhone'.

'I Phone' was registered in March 1998, and 'IPhone' was registered in 1999. Since then, the I PHONE mark had been abandoned.

Infogear trademarks cover 'communications terminals comprising computer hardware and software providing integrated telephone, data communications and personal computer functions' (1993 filing), and 'computer hardware and software for providing integrated telephone communication with computerized global information networks' (1996 filing). Infogear released a telephone with an integrated web browser under the name in 1998. In 2000, Infogear won an infringement claim against the owners of the iphones.com domain name. In June 2000, acquired Infogear, including the iPhone trademark.

On December 18, 2006, they released a range of re-branded (VoIP) sets under the name iPhone. In October 2002, Apple applied for the 'iPhone' trademark in the United Kingdom, Australia, Singapore, and the European Union. A Canadian application followed in October 2004, and a New Zealand application in September 2006. As of October 2006, only the Singapore and Australian applications had been granted. In September 2006, a company called Ocean Telecom Services applied for an 'iPhone' trademark in the United States, United Kingdom and Hong Kong, following a filing in Trinidad and Tobago.

As the Ocean Telecom trademark applications use exactly the same wording as the New Zealand application of Apple, it is assumed that Ocean Telecom is applying on behalf of Apple. The Canadian application was opposed in August 2005, by a Canadian company called who themselves applied for the trademark three months later. Comwave has been selling VoIP devices called iPhone since 2004. Shortly after Steve Jobs' January 9, 2007 announcement that Apple would be selling a product called iPhone in June 2007, Cisco issued a statement that it had been negotiating trademark licensing with Apple and expected Apple to agree to the final documents that had been submitted the night before.

On January 10, 2007, Cisco announced it had filed a lawsuit against Apple over the infringement of the trademark iPhone, seeking an injunction in federal court to prohibit Apple from using the name. In February 2007, Cisco claimed that the trademark lawsuit was a 'minor skirmish' that was not about money, but about interoperability. On February 2, 2007, Apple and Cisco announced that they had agreed to temporarily suspend litigation while they held settlement talks, and subsequently announced on February 20, 2007, that they had reached an agreement. Both companies will be allowed to use the 'iPhone' name in exchange for 'exploring interoperability' between their security, consumer, and business communications products. The iPhone has also inspired several leading high-tech clones, driving both the popularity of Apple and consumer willingness to upgrade iPhones quickly. On October 22, 2009, filed a lawsuit against Apple for infringement of its GSM, UMTS and WLAN patents. Nokia alleges that Apple has been violating ten Nokia patents since the iPhone initial release.

In December 2010, reported that some iPhone and users were suing because some applications were passing user information to third-party advertisers without permission. Some makers of the applications such as Textplus4,,,, Talking Tom Cat and Pumpkin Maker have also been named as co-defendants in the lawsuit. In August 2012, Apple won a in the U.S. Against, the world's largest maker of smartphones; however, on December 6, 2016, reversed the decision that awarded nearly $400 million to Apple and returned the case to Federal Circuit court to define the appropriate legal standard to define 'article of manufacture' because it is not the smartphone itself but could be just the case and screen to which the design patents relate.

In March 2013, an Apple patent for a wraparound display was revealed. Secret tracking Since April 20, 2011, a file on the iPhone and other iOS devices has been widely discussed in the media. It was alleged that the file, labeled 'consolidated.db', constantly stores the iPhone user's movement by approximating geographic locations calculated by, a technology proven to be inaccurate at times. The file was released with the June 2010 update of Apple and may contain almost a year's worth of data. Previous versions of iOS stored similar information in a file called 'h-cells.plist'.

Discovered that the data is transmitted to Apple twice a day and postulate that Apple is using the information to construct their global location database similar to the ones constructed by Google and through. Nevertheless, unlike the 'Latitude' application, which performs a similar task on phones, the file is not dependent upon signing a specific or even the user's knowledge, but it is stated in the 15,200 word-long of the iPhone that 'Apple and [their] partners and licensees may collect, use, and share precise location data, including the real-time geographic location of [the user's] Apple computer or device'. The file is also automatically copied onto the user's computer once synchronized with the iPhone. An application named 'iPhoneTracker', which turns the data stored in the file into a visual map, was made available to the public in April 2011. While the file cannot be erased without the phone, it can be encrypted. Apple gave an official response on their web site on April 27, 2011, after questions were submitted by users, the and others. Apple clarified that the data is a small portion of their crowd-sourced location database cache of Wi-Fi hotspots and cell towers which is downloaded from Apple into the iPhone for making location services faster than with only GPS, therefore the data does not represent the locations of the iPhone.

The volume of data retained was an error. Apple issued an update for iOS (version, or for the CDMA iPhone 4) which reduced the size of the cache, stopped it being backed up to iTunes, and erased it entirely whenever location services were turned off. The upload to Apple can also be selectively disabled from 'System services', 'Cell Network Search.' Regardless, in July 2014, a report on state-owned China Central Television labeled the iPhone a 'national security concern.' A feature that can be found under 'location services' in the settings of the iPhone has also been found to be secretly tracking the user's information. This feature is called 'frequent locations' and it can either be kept on or turned off. This feature is said to help the accuracy of the GPS and Apple Maps since it can log information about the locations the user has frequently visited.

However, this feature also keeps track of the number of times that the user has been to that location, the dates, and the exact times. A lot of people have found this feature to be intrusive of their personal lives and have since then had an option to keep it on or shut it off. Encryption and intelligence agency access It was revealed as a part of the that the American and British intelligence agencies, the (NSA) and the (GCHQ) have access to the user data in iPhones, BlackBerrys, and Android phones, respectively. They can read almost all smartphone information, including SMS, location, emails, and notes. According to an article in titled 'Signaling Post-Snowden Era, New iPhone Locks Out N.S.A.' , Apple has developed a new encryption method for iOS 8, described as 'so deep that Apple could no longer comply with government warrants asking for customer information to be extracted from devices.' Throughout 2015, prosecutors in the United States argued for the U.S.

Government to be able to compel decryption of iPhone contents. After the, the recovered an that was issued to one of the shooters by his employer, and backups of that phone from a month and a half before the shooting. (The shooters had destroyed their personal phones.) The U.S. Government attempted to use the arcane and outdated to obtain a court order ordering Apple to produce an file that would allow investigators to brute force the passcode of the iPhone, which would equate to modernized slavery. Responded on the company's website, outlining a need for encryption, arguing that if they produce a for one device, it would inevitably be used to compromise the privacy of other iPhone users. On February 19, Apple communicated to journalists that the password for the Apple ID for the iPhone had been changed within a day of the government obtaining it, preventing Apple from producing a workaround that would only target older devices.

As of April 2016, Apple's Privacy Policy addresses requests from government agencies for access to customers' data: 'Apple has never worked with any government agency from any country to create a “backdoor” in any of our products or services. We have also never allowed any government access to our servers.

And we never will.' In 2015 the awarded Apple 5 out of 5 stars “commend[ing] Apple for its strong stance regarding user rights, transparency, and privacy.” Restrictions. See also: Apple tightly controls certain aspects of the iPhone. According to, the emergence of like the iPhone have made computing more than early versions of.

The community has found many workarounds, most of which are disallowed by Apple and make it difficult or impossible to obtain warranty service. ' allows users to install apps not available on the App Store or modify basic functionality.

SIM unlocking allows the iPhone to be used on a different carrier's network. However, in the United States, Apple cannot void an iPhone's warranty unless it can show that a problem or component failure is linked to the installation or placement of an after-market item such as unauthorized applications, because of the 's. The iPhone also has an area and settings where users can set restrictions or parental controls on apps that can be downloaded or used within the iPhone. The restrictions area requires a password. Activation The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007, reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone's other features with a combination of custom software and modification of the iTunes binary.
