Redsn0w Rerun Untethered iOS 4.2.1 Jailbreak
If you are not satisfied like most of us with tethered iOS jailbreak then get ready for next Redsn0w version, which will bring you the Untethered iOS 4.2.1 jailbreak without requiring restore.
MuscleNerd: Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for “backup plan” 4.2 untether
MuscleNerd: @jkurtz87 it shouldn’t require a restore…just another redsn0w run. (That’s the goal!)
As in the tweet above the hard work behind untethered iOS 4.2.1 is courtesy of Comex, who is busy developing the tool for the latest iOS firmware.
