Did you know about it.

It's been around for a while now..
Most people know about it. It is a combo of a phone, the internet, and an mp3 player

The iPhone is a line of Internet and multimedia-enabled smartphones designed and marketed by Apple Inc. The first iPhone was unveiled by Apple CEO Steve Jobs on January 9, 2007. The phone was released on June 29, 2007. An iPhone can function as a video camera, a camera phone with text messaging and visual voicemail, a portable media player, and an Internet client with e-mail 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 350,000 "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.
