The iPhone (pronounced /ˈaɪfoʊn/ eye-fone) is a line of Internet– and multimedia-enabled smartphones designed and marketed byApple Inc. The first iPhone was unveiled by Apple CEO Steve Jobs on January 9, 2007,[1] and released on June 29, 2007.

An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), acamera phone, can send texts and receive visual voicemail, a portable media player, and an Internet client with email and web browsing capabilities, and both Wi-Fi and 3G connectivity. The user interface is built around the device’s multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple application software is available from the App Store, which launched in mid-2008 and now has over 425,000[2] “apps” approved by Apple. These apps have diverse functionalities, including gamesreferenceGPS navigationsocial networking, security and advertising for television shows, films, and celebrities.

There are four generations of iPhone models, each accompanied by one of the four major releases of iOS (formerly iPhone OS). The original iPhone was a GSM phone that established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video recording at 480p. The iPhone 4 has a rear facing camera and a front facing camera (at a lower resolution) for FaceTime video calling and for use in other apps like Skype. The phone also featured a higher-resolution display; it was released on June 24, 2010. In the U.S., AT&T was the only authorized carrier until February 10, 2011, when a CDMA version of the iPhone 4 launched for Verizon.
