  • "Backup Plan:" Untethered 4.2.1 JB Coming for All Devices
    [ame=http://www.youtube.com/watch?v=WVZ5MDPVHWU]YouTube - Untethered 4.2.1 JB on ipt4g[/ame]


    A tweet from @MuscleNerd last night revealed a workaround he's done for an untethered jailbreak of iOS 4.2.1 on the fourth-gen iPod touch. Using saved SHSH blobs from 4.2 beta 3, the method doesn't use expose any of the known holes that are used in the current set of exploits: it's a "backup plan" to the userland method that @comex is working on.



    @MuscleNerd's method can be generalized for use with all devices (including the Apple TV 2G) and is reusable for future jailbreaks. @comex's method is, he says, "more extensible" though.

    No updates yet as to when this will be released, but we'll let you know as soon as we find out.

      LOL

      It must be hereditary in my family because it's taking my nephew forever to get his too. Kids these days are asking for iPod touches for Christmas. Boy things are expensive. I remember when a big wheel was $25 and Transformers was $5 to $10.

      On a positive note, how was the performance? Is it worth upgrading to at all?
      Not all of us wanted to upgrade to 4.2.1 I for one had to restore so I thought what the he'll I got my shsh stored but still can't downgrade even after changing host etc think before you post
      On second note new text tones AirPrint not worth upgrading to be honest

      I updated my iPhone 4 to 4.2.1 before I knew there was not an untethered JB out there, so I hope this is released soon!

      I did think before I posted. I was referring to people who intentionally upgraded to JB with the tethered JB. I meant no disrespect. I feel your pain since you had to restore

      Well here's a little story of little importance, but what the hell!

      When I first had bought my 3G[S] last year during about September, I remember I was so pissed off because upon reading if it was an old bootrom or newer one. (I didn't even know 3G[S]'s had this 'new'/'old' bootrom fiasco going on, nor what a 'tethered jb' meant.)

      Well, my 3G [S] all pointed to the fact that it was the new bootrom. (At that time, I thought if it was simply in the MCxxxx format meant it was a new bootrom) there wasn't much talk at the time of new bootroms, old ones, blah blah, and from reading posts with the same model, it all pointed to the fact that it was indeed the new one, I thought I was screwed.

      To cut things short, I ended up taking the plunge, jailbroke it, found out it was the old bootrom, and this is what has made me love my 3G [S] even more. Never even knew it was so rare, but i'm very sure there are tons 'among' us.

      I have my blobs saved from 3.1.2 onwards, but my BB still has been preserved to 5.11.07. The hardest part was probably figuring out how to update to 4.2.1 while preserving it, but all is good.
