It is now possible to jailbreak the iPhone OS 3.1.2 firmware thanks to the blackra1n software. So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n. As usual, do not update your iPhone firmware via iTunes if you jailbreak your iPhone / iPod (all data will be erased)
Download the blackra1n from here (click on the windows logo)
