iPhone is an internet-connected multimedia smartphone designed and marketed by Apple 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. iPhone functions as a camera phone (including text messaging and visual voicemail), a portable media player (equivalent to an iPod), and an Internet client (with email, web browsing, and local Wi-Fi connectivity). The first-generation phone hardware was quad-band GSM with EDGE; the second generation also adds UMTS with HSDPA.

Apple announced iPhone on January 9, 2007. The announcement was preceded by rumors and speculation that circulated for several months. 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.
