The iPhone Dev Team have kind of missed the Christmas deadline to release the untethered iOS 4.2.1 jailbreak. The new version of Mac and Windows based tool – redsn0w is expected to jailbreak all new generation of devices – iPad, iPhone 4 and iPod touch 4G. Though the jailbreak isn’t ready for public release the iPhone Dev Team has laid out plans for some private testing iOS 4.2.1 jailbreak.
Untethered jailbreak for iOS 4.2.1 running devices was demonstrated via video by the iPhone Dev Team. It was more of a “backup plan” since it users the iOS 4.2 beta 3 SHSH blobs stored with Cydia.  Another team member comex was said to be working an extensible version – means a way to retain the exploits for future usage and use the final iOS 4.2.1 build for jailbreaking.

Right now, the “backup plan” requires that you have the 4.2b3 IPSW on your Mac, and that Cydia has your 4.2b3 SHSH hashes.  Please don’t pirate that 4.2b3 IPSW!  (We’re also working on a way that this technique might apply to all those with 4.1 IPSWs, but that’s not the first goal right now.)
Mac owners who wish to help the iPhone Dev Team to test the “Backup Plan” version of redsn0w to jailbreak all new iOS 4.2 devices should follow @redsn0w_testers on Twitter.  The interested folks are being reminded that their iPhones may lose the ultrasn0w unlock to test out this jailbreak. With Mac only testing happening this weekend, we can expect the userland jailbreak tool to be released any time next week or at the new years eve – yeah, the iPhone Dev Team tends to be dramatic at such occasions at times.
