The iPhone is a line of smartphones designed and marketed by Apple Inc. It runs Apple's iOS mobile operating system. The first generation iPhone was released on June 29, 2007 the most recent iPhones, the seventh-generation iPhone 5C and iPhone 5S, were introduced on September 10, 2013.
The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and cellular connectivity (2G, 3G, 4G, and LTE). An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, and receive visual voicemail. Other functions — video games, reference works, GPS navigation, social networking, etc. — can be enabled by downloading application programs (‘apps’); as of October 2013, the App Store offered more than one million apps by Apple and third parties.
There are seven generations of iPhone models, each accompanied by one of the six major releases of iOS. The original 1st-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted through all models and a screen size maintained for the next four iterations. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960×640 "Retina Display", a VGA front-facing camera for video calling and other apps, and a 5-megapixel rear-facing camera with 720p video capture.[19] The iPhone 4Supgrades to an 8-megapixel camera with 1080p video recording, a dual-core A5 processor, and a natural language voice control system called Siri. IPhone 5 features the dual-core A6 processor, increases the size of the Retina display to 4 inches, and replaces the 30-pin connector with an all-digital Lightning connector. The iPhone 5S features the dual-core 64-bit A7 processor, an updated camera with a larger aperture and dual-LED flash, and the Touch ID fingerprint scanner, integrated into the home button. iPhone 5C features the same A6 chip as the iPhone 5, along with a new backside-illuminated FaceTime camera and a new casing made of polycarbonate. As of 2013, the iPhone 3GS had the longest production run, 1181 days; followed by the iPhone 4, produced for 1174 days.
The resounding sales of the iPhone have been credited with reshaping the smartphone industry and helping make Apple one of the world's most valuable publicly traded companies in 2011–12. The iPhone is the top-selling phone of any kind in some countries, including the United States and Japan.
History and availability
Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1000 employees to work on the highly confidential "Project Purple", including Sir Jonathan Ive, the designer behind the iPhone. Apple CEO Steve Jobs steered the original focus away from a tablet, like the iPad, and towards a phone. Apple created the device during a secretive collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months.
Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house and even paid Apple a fraction of its monthly service revenue (until the iPhone 3G), in exchange for four years of exclusive US sales, until 2011.
Jobs unveiled the iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco. The two initial models, a 4 GB model priced at US$ 499 and a 8 GB model at US$ 599, went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide. The passionate reaction to the launch of the iPhone resulted in sections of the media dubbing it the 'Jesus phone'. The 1st generation iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.

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 have household incomes over US$100,000.
The back of the original 1st 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 GSM 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 aluminosilicate glass front and back with a stainless steel edge that serves as the antennas. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.
The iPhone has garnered positive reviews from such critics as David Pogue and Walt Mossberg. The iPhone attracts users of all ages, and besides consumer use, the iPhone has also been adopted for business purposes.
Users of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way. This became known as antennagate.
