Redsn0w Untethered Jailbreak for iOS 4.2.1 Will Be Released On Christmas [Confirmed] [Updatex1]

Few moments ago @Musclenerd has confirmed the release of untethered iOS 4.2.1 jailbreak for the Christmas Eve and asking for Mac OS X owners to help them with testing the the backup plan.

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!

So what you think? if you fit all the requirements mentioned above, you are good to go!


Musclenerd stated on his blog that:

The idea is, we’ll use that Twitter account to push out trial software. then you guys can give us feedback here on this page.

This means that the Backup Plan will be released soon on the Twitter Account which was mentioned to follow. If you missed it so click here and grab it. They post the release on that account on twitter for Testers and do read the requirements needed for the Testing of Redsn0w on ios 4.2.1.

Stay Tuned with us we will update you!
