Well, well… Dev-Team has done it again. Even a virgin 3.1.2 iPhone can now be jailbroken. This just shortly after rumors Apple will soon release new hardware that is “un-jailbreakable”.
Version 3.1.4 of PwnageTool supports the 3.1.2 release of the iPhone software for iPhone 2G/3G/3GS and iPod Touch 1G/2G.
Caution: Please head over to the dev-team blog, read and then re-read the instructions and warning before upgrading.
