It invalidates warranties and flies against user agreements, but jailbreaking iPhones remains a technical challenge that appeals to the self-same sorts of technical problem-solving types who first hung out at the HomeBrew Computer Club or put together Black Box telephone jammers with help from Cap’n Crunch: so the news here is that hacker geohot, has just released a new version of Blackra1n, his 30-second jailbreak tool.

  Blackra1n RC2 now supports all device models, including the newer versions of the iPhone 3GS and iPod touch, says Cult of Mac. Among other things, it adds support for the new iPhone 3GS and the iPod touch 8GB.

There’s lots of bug fixes, but does not unlock the device, only offering jailbreaking. Oh, and the software works n Windows and Mac.

From geohot’s blog:

Update – RC2 is out
Fixed 3G issues;
Tethered jailbreak for 3.1 OOTB ipt 8GB and new 3GSes;
Fixed Icy issues;
Both Windows and Mac;
If you used RC1 with success, no need to rerun.

If you are curious to unlock or jailbreak your iPhone or iPod touch, please ensure you fully understand what you have to do and you are prepared to void your warranty or otherwise bear the consequences of what you’re doing.
