About
The iPhone is an internet-connected, multimedia smartphone designed and marketed by Apple Inc. Since its minimal hardware interface lacks a physical keyboard, the multi-touch screen renders a virtual keyboard when necessary. The iPhone functions as a camera phone (also including text messaging and visual voicemail), a portable media player (equivalent to a video iPod), and an Internet client (with email, web browsing, and Wi-Fi connectivity).Apple announced the iPhone on January 9, 2007
