The title of the post says it all. Doesn’t it? Anyways, we are here to share with you the news you have been wanting to hear. MuscleNerd of the iPhone Dev Team has announced that they will be rolling out an updated version of redsnow during this weekend, Christmas weekend that is, which will bring the long awaited untethered jailbreak for iOS 4.2.1.

iOS 4.2.1 untethered jailbreak
Currently the iPhone Dev Team is looking for Mac testers to try out the redsn0w before the final version goes public:

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!
(If you have an iPhone 3G, or an old-bootrom ipt2g or iPhone 3GS, you already have an untethered jailbreak!  Just use the latest public redsn0w.)

To keep things manageable, this will be a Mac-only test program.  We also request that any volunteers *NOT* need the ultrasn0w unlock (in case things go very wrong).

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.)

If you fit all the above qualifications, please follow @redsn0w_testers on twitter for announcements, and use the comments section here for feedback.  Thanks very much for your help, and Happy Holidays!

Update 1: The iPhone Dev Team has rolled out a beta version of redsn0w 0.9.7 which brings the untethered jailbreak for iOS 4.2.1. Details here.
