iPhone

The iPhone (commonly known as the "iPhone 2G") was Apple's first smartphone. It was announced on 2007-01-09 and released on 2007-09-29.

The iPhone used many "off the shelf" components

Name

When announced and released, the iPhone 2G was simply called iPhone. However, with the release of the iPhone 3G in 2008, the original iPhone became commonly known as the "iPhone 2G." The reasoning is believed to be two-fold: it is the iPhone preceding the "3G" (and 2 is one before 3), and it only supported GSM and EDGE networks (commonly called "2G" networks).

Hacking

Naturally, as a first generation device, the original iPhone is one of the more "hack-friendly" iDevices. Within two months of its release, geohot (George Hotz) "unlocked" the AT&T only phone to work on T-Mobile. A few months later, the iPhone Dev Team discovered "Pwnage," a bootrom level untethered exploit that allowed jailbreaking the device on any version of iPhone OS.
