Dev Team has done it again. iPhone 3.1 OS has been jailbroken for iPhone 3GS and iPod Touch 2 machines, in case you’re Mac users. Mind you, this new Pwnage 3.13 tool, the team has released, will not work with Phone/iPod Touch devices that came out-of-the-box with OS 3.1 or were upgraded via iTunes. In other words, you have to Pwnd them at 3.0 or 3.0.1 versions, before jumping to the latest one.
