  • "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.

      Don't know. That model is always the hardest to get support for.

If I were to update and jailbreak (tethered) to 4.2.1 using the latest redsn0w, would I be able to later when it's released, jailbreak 4.2.1 untethered? or would it be more complicated then that in the long run? Basically what would make it worth jailbreaking tethered to 4.2.1 for me?
      Don't jailbreak tethered, it's not worth it unless you NEED to jailbreak it. I've been hearing theres gonna be an untethered jailbreak before christmas. wait and sit tight

      I'm still wondering if there will be a JB for new devices since the new phones come loaded with 4.2... I don't want to upgrade and lose all my cydia stuff...
