Essentially a converged iPod touch and Mac OS powered smartphone, the original Apple iPhone changed the smartphone market forever when it was released in 2007.
The face of the iPhone is dominated by its 3.5" touchscreen display. The Home button centered below the screen always takes you back to the main
menu and is the only hardware control on the unit's face. The iPhone does not include a stylus; interacting with the mobile
Mac OS is the venue of the iPhone's touch/gesture interface, which is designed for fingertips rather than styli. Even the iPhone's keyboard is touchscreen-based.
The iPhone works much like an iPod, syncing with iTunes for music, movie and TV downloads, contacts, calendar entries and more. The iPhone also syncs with Outlook on Windows PCs.
The 1st Gen iPhone has onboard Wi-Fi and Bluetooth 2.0, and connects to the AT&T Mobility service via GSM/EDGE. The Safari web browser renders web pages as they were designed to be seen, even on a small screen. New applications can also be added to the iPhone via the web browser with "Web 2.0" functionality over the wireless network; the iPhone 2.0 OS added third-party Apps.
