Updated Redsn0w will Untether Jailbreak iOS 4.2.1 to be Released on Christmas Day!

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

@comex mentioned in his tweeter a few days ago that he will miss the Christmas deadline of releasing a more efficient userland-based untethered jailbreak for iOS 4.2.1.

On the other hand, @MuscleNerd will deliver the untethered jailbreak for iOS 4.2.1 with the updated version of ultrasn0w. He asked people to participate in testing the updated ultrasn0w before the official release this Christmas weekend. See below for the requirements:

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!

At the writing of this blog post there are already 6,021 followers and 61 listings on @redsnow_testers.

It’s the holiday season but the work never stops in the jailbreaking world and we thank you for all your hard work!

Share this and be awesome!
