iPhone Dev Team Announces Plan To Release Untethered iOS 4.2.1 Jailbreak, iOS 4.2 Beta 3 IPSW Required

Hey guys, the iPhone Dev Team have finally announced the launch of their untethered iOS 4.2.1 jailbreak. Apparently, for now, it will be Mac OS X only and it will require you to have the official 4.2 beta 3 ipsw that official developers (like us and all of those who signed up with us when we were offering spots in our development account should have) as well as the 4.2 beta 3 SHSH.

Also, they are urging people who require ultrasn0w to refrain from using the software, also, they urge people to not pirate the 4.2 beta 3 ipsw software file, they will be working on a way for the same method to work with the 4.1 ipsw.

A restore is not needed for this untethered jailbreak as all you have to do is run redsn0w and it will untether it. The new Mac-Only redsn0w will arrive “over the holiday weekend.

The untether will work with iPhone 3G [S] (new bootrom), iPod touch 2G (MC Model), iPod touch G3, iPod touch G4, iPhone 4, and iPad.

Here’s the official press release:
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!
