Geohot aka George Hotz aka the first person to unlock the original iPhone (with solder), has released a jailbreak for the iPhone 3GS. And, the naughty boy, he has taken the work done by the iPhone Dev Team (the folks behind all previous software unlocks) and posted it early.

The iPhone Dev Team are waiting for the v3.1 software release from Apple before “officially” making the hack available, ostensibly to avoid the hack being patched by Apple . But as it is already ready, Geohot, a member of the Dev Team, has gone ahead and put it out for download.

The unlock is Windows-only, and you’ll need an iPhone 3GS to use it on, of course. I have neither, so I can’t test it, but GeoHot at least has a good reputation. According to The Register, Hotz says the hack, named “purplera1n” is “awesome.” Maybe, but if it lets you load up the carrier-unlocking applications available for jailbroken iPhones. we’ll probably agree.
