You'll love iPhone

The iPhone is an internet-connected, multimedia smartphone designed and marketed by Apple Inc. Because 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 include text messaging and virtual voicemail), a portable media player (equivalent to a video iPod), and an internet client (with email, web browsing, and Wi-Fi connectivity). The first-generation phone hardware was quad-band GSM with HSPDA.
