The iPhone is a line of Internet and multimedia-enabled smartphones designed and marketed by Apple Inc.
An iPhone can function as a video camera, camera phone with text messaging and visual voicemail, a portable media player, and an Internet client with e-mail, web browsing, 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 applications are available from the App Store, which launched in mid-2008 and now has well over 300,000 "apps" approved by Apple. These apps have diverse functionalities, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.
