    Update #1: redsn0w version 0.9.6b4 is now available for your 4.2.1 jailbreaking pleasure

    per dev-team website after seeing the update on twitter

    sorry cant post the link...not enough posts yet


    Thanksgiving with Apple
    With Turkey Day a few days off, today Apple publicly released FW version 4.2.1. As always, ultrasn0w unlockers please stay far far away from this official firmware (and all official firmware). Wait for the ability to create custom 4.2.1. IPSWs that dont update your baseband! If youre not an unlocker, read on!

    The best news of all is for owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G. Due to a combination of our original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is just as jailbreakable as ever. You reap the full benefit of an untethered 4.2.1 jailbreak.

    Next are the owners of all the more recent devices. The good news there is that due to geohots limera1n exploit, all recent devices can be jailbroken (this will be true until Apple released new hardware that fixes geohots limerain exploit in the bootrom). The bad news is that right now, the 4.2.1 jailbreak is *tethered* on all of these recent devices. A tethered jailbreak means that each time your device loses battery power or needs to be rebooted, you must attach it to a PC or Mac to boot into the jailbroken state. @comex is working hard on a method that may untether the 4.2.1 jailbreak, but it will require you to have your 4.1 SHSH blobs in order to use it. No word on how much more effort it will take though (please dont bug @comex about it!). (We also have an alternative method that may work, but @comexs method is much more elegant.)

    So when does all this 4.2.1 jailbreak action happen? *)*Well if youre a JB developer or tinkerer, youve already probably used the redsn0w mentioned in our last post to jailbreak 4.2.1 and at least get SSH working. But beyond that, there are still some last minute issues with MobileSubstrate and comexs kernel patches that are being fixed. Well tweet and post a blog update when its all available (we hate to give ETAs, but barring any unforeseen problems, probably later today).*** It happens nowsee Update #1.

    In the meantime, please make sure you have your 4.1 SHSH blobs for all your devices. These will be important even for firmware beyond 4.1 (using both comexs method and our alternative, depending on how each of them turn out.)

    ultrasn0w unlock: After redsn0w is officially released with the new Cydia and kernel patches, well be able to assess the unlock situation. Its already looking very promising though, so expect the unlock for the 3G and 3GS to be coming this week. The i4 unlock is taking more effort though, and no further concrete info is available about that yet.

    Feel free to ask questions in our comments section below, where weve got some awesome new additional moderators sherif_hashim, dhlizard, and Frank55!

    Update #1: redsn0w version 0.9.6b4 is now available for your 4.2.1 jailbreaking pleasure. Please read all the above to understand what this jailbreak currently entails.
