An old exploit that worked to control the iPod Touch 2G can be used to take control of the iPhone 3GS, ensuring that carrier unlockers will soon be able to crack their fancy new phones. It seems a piece of boot code was left unaltered since August 2008, allowing the Dev Team to use an old exploit.

The original announcement of the iPod Touch 2G jailbreak mentions that this could be an untethered break which does not require users to connect their iPhone to a computer to run the jailbreak. Noice.
