GeoHot the original iPhone hacker is back at it again with an untethered jailbreak for the iPhone, iPod Touch, and possibly even the iPad.
Currently some of the newer jailbreak methods required you took hook your iPod back up to your computer every time you restarted. This is a real hassle for many people. Say your iPod freezes and you have to restart. You would have to hook the iPod up to a computer before you could use it.
This new method that GeoHot will be releasing soon may possibly work on the iPad but will most likely be killed by the next software update which I expect we will see soon after the iPad release.
