Champion of the people or show-off hacker - you decide - George Hotz says he has created a new, untethered jailbreak for the latest iPhones.
"The jailbreak is all software based, and is as simple to use as blackra1n," says Hotz, aka Geohot, on his blog.
He hasn't released it yet - and says he doesn't want to be hassled - but says it will work for the iPhone 3GS and second and third generation iPod Touches.
It might even work on the iPad, as this runs an enhanced version of the iPhone OS - Hotz says it "probably" will.
There's a video of him in action, here.
