Dev-Team Untethers Pwnage Tool iPhone Jailbreak 4.2.1 / 4.2.6
iPhone Dev-Team has packaged the jailbreak solution released by Chronic Dev Team along with some extra features into Pwnage Tool 4.2. This latest incarnation of Pwnage Tool provides an untethered jailbreak on Mac OS X for all recent iOS devices running firmware 4.2.1 and the Verizon iPhone running 4.2.6.
One key advantage of using the Pwnage Tool will appeal to unlockers, as these individuals can safely restore to a custom 4.2.1 IPSW while keeping their current baseband and unlock. Two problems that were reported with the GreenPois0n jailbreak have also been fixed, including iBooks not opening as well as Wi-Fi issues on the Apple TV 2.
Apple has reportedly been blocking users from reading purchased books if their devices are jailbroken. Dev-Team members @comex and @pushfix have fixed this problem and now DRM-protected books should work just fine regardless of whether your iPhone is jailbroken. Also, Wi-Fi problems on jailbroken Apple TV 2 units have been fixed by developers @nitotv, @DHowett and @saurik. Both of these improvements are included in Pwnage Tool 4.2, but if you're already jailbroken there's no need to do it again. They will soon be available as patches on Cydia.
To recap, Pwnage Tool 4.2 will jailbreak the iPhone 3G, iPhone 3GS, iPhone 4, Verizon iPhone 4, iPod touch 3G, iPod touch 4G, iPad and Apple TV 2. Get the latest Pwnage Tool along with more information directly from the iPhone Dev-Team.
Worried about the upcoming launch of iOS 4.3? The exploits used for the untethered 4.2.1 / 4.2.6 jailbreak have already been closed in iOS 4.3 developer beta firmware, however according to the iPhone Dev-Team, security researcher @i0n1c has an untethered jailbreak solution ready to go for when Apple launches the final version. Sounds like those looking forward to an untethered 4.3 jailbreak won't be waiting very long after the Apple release.
