According to MuscleNerd, the next version of Redsn0w, which will be versioned as Redsn0w 0.9.6 b7 or most probably Redsn0w 0.9.7, will not only bring untethered jailbreak on iOS 4.2.1 for non-jailbroken idevices but also perform untethered jailbreak for already jailbroken (tethered) devices on iOS 4.2.1.
The most important feature in Redsn0w 0.9.7 will be to provide untethered jailbreak support without needing to restore iOS 4.21 on already jailbroken idevices. All you will have to do is to re-run the Redsn0w and it will be done!
The main advantage of this will be that you won’t need to re-install any app/game from AppStore or Cydia.
jkurtz87: @MuscleNerd like if your tethered now can new redsn0w when released make untethered or fully restore (which is best choice)
MuscleNerd: @jkurtz87 it shouldn’t require a restore…just another redsn0w run. (That’s the goal!)
Some other features which may include in upcoming Redsnow version are:
MuscleNerd: Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for “backup plan” 4.2 untether
MuscleNerd: This latest @comex code also allows retrieval of photos+files stuck behind an unfixable filesystem problem…good stuff!
