Just when we reported that Comex told us he did not think he would meet his Christmas deadline, the Dev-Team have proved this statement to be flawed. They have just updated their official blog, to include a post that states they will currently be accepting beta testing applicants to test a new version of RedSn0w. This new version of RedSn0w includes a a new feature called a “backup plan”, which will serve the purpose as an untethered jailbreak for the iOS4.2.1 firmware. The RedSn0w untethered update will be released over the Christmas weekend (meaning it may not be released on Christmas), and as this is an official post by the Dev-Team and not just a twitter update, we can confirm this to be a reliable source.

Here is the official blog post below…

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!

We will write up a tutorial as soon as this RedSn0w update is released, so please stay tuned! Until then, are you excited for an untethered jailbreak?
