RedSn0w Untethered Jailbreak For iOS 4.2.1 Releasing Tomorrow

Comex from the iPhone Dev Team had only recently revealed that the untethered jailbreak for iPhone 4 and the other new generation iDevices could be delayed. But here is some good news if you had been desperately looking for an update from the Dev Team. We have now heard from MuscleNerd, the popular iPhone hacker who is part of the team that an alternative untethered solution will now be released on Christmas day. He has said,

“Over the Christmas weekend we’ll be releasing a version of redsn0w that implements the “backup plan” to the 4.2.1 untethered jailbreak.  We’re seeking your help to test this redsn0w and find any bugs before we do a general release!”

Some points to note here if you are willing to volunteer as a tester. Firstly, this will be a Mac-only test program. Secondly, those users who need an UltraSn0w unlock may run the risk of losing their unlock and are hence advised against volunteering. He further notes,

“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.)”

Details regarding the test program is expected to be available on a new Twitter account @redsn0w_testers. In any case, the public release is scheduled for just a day from now. So get ready to jailbreak this weekend.
