This is the original iPhone. It was released on 29 June 2007. It is an internet-connected smartphone designed and manufactered by Apple Inc. with a multi-touch screen. It does not have a physical keyboard, so a virtual keyboard is rendered on-screen. The first generation includes Quad-Band GSM with EDGE. The board configuration is M68AP and the name used in firmware is iPhone1,1.
The iPhone uses the S-Gold 2 baseband chip.
Uses the CSR BlueCore4 Chip (BC41B41)
Naturally, as the iPhone was a first generation device, it is one of the more hack-friendly iDevices. It is susceptible to Pwnage 2.0 for an untethered jailbreak, and will remain that way since it is a hardware-based exploit. The iPhone unlock is also available and is unfixable by Apple. The iPhone Dev Team created BootNeuter which can remove restrictions the Baseband Bootloader imposes and unlock the iPhone no matter what.
