iPHONE

The iPhone is an internet-connected multimedia smartphone designed and marketed byApple Inc. with a flush multi-touch screen and a minimal hardware interface. The device does not have a physical keyboard, so a virtual keyboard is rendered on the touch screen instead. The iPhone functions as a camera phone (including text messaging and visual voicemail), a portable media player (equivalent to an iPod), and Internet client (with email,web browsing, and local Wi-Fi connectivity). The first generation phone hardware wasquad-band GSM with EDGE; the second generation also adds UMTS with HSDPA. Apple announced the iPhone on January 9, 2007. The announcement was preceded byrumors and speculation that circulated for several months. The iPhone was initially introduced in the United States on June 29, 2007 and has since been introduced worldwide. It was named Time magazine's "Invention of the Year" in 2007. On July 11, 2008, the iPhone 3G was released. It supports faster 3G data speeds and Assisted GPS.
