Finally MuslceNerd has confirmed through his twitter account that “Plan B” iOS 4.2.1 untethered jailbreak with Redsn0w 0.9.6b7 for iPhone 3GS New Bootrom, iPhone 4, iPod Touch 4 etc will be available to download and test on Christmas.
The developer has suggested that only those iPhone users who don’t rely on unlock should test this untethered jailbreak.
Initially Redsn0w 0.9.6b7 will be released for Mac users only and after positive feedback, Windows version of Redsn0w will also be made available for download.
As we have already told you in our previous post that “Plan B” untethered jailbreak requires SHSH blobs of iOS 4.2b3 to work, so if you didn’t save the hashes for the said iOS version, don’t try this method.
Here the complete update from iPhone Dev Team:
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!
Stay tuned to this site for latest updates as they happen.

when i PRESS save SHSH I KEEP GETING THIS MASSAGE You have saved your iPhone4 4.2.1 (8C148) SHSH locally and the request was sent to CYDIA. This means that CYDIA DOES have your SHSH. Do NOT bug semaphore about the Cydia home page showing this version.
where do we get 4.2b3 SHSH hashes
From Cydia servers. Open the Cydia and see if the hashes are saved for iOS 4.2 b3. If not, this method is not for you.
Its only for THE iPhone 4 touch and another one not for 3gs new bootrom
Its only for iPhone 4, iPod Touch 4G and iPad.
