Just days after the public release of iOS 4.2.1, the iPhone Dev-Team released a jailbreak which allowed iOS devices running the latest firmware to be jailbroken. However, some devices, such as the iPhone 4, the latest iPod Touch, and the iPad, require a tethered jailbreak that meant you to had to connect your device to iTunes in order to boot it up.
This may not be the case for much longer, as Dev-Team member MuscleNerd announced on Twitter today that the team are hard at work creating an untethered jailbreak for all devices. He explained that Dev-Team pal Comex is working on a more “extensible” untethered jailbreak, but that he has a “backup plan” if all else fails.
“Got “backup plan” for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you,” read MuscleNerd’s first tweet, which was followed up by, “(It’s a “backup plan” because comex is working on a more extensible one, but this method is also generalizable).”
The video below was released by MuscleNerd today and shows the an iPod Touch 4th-generation device taking advantage of his untethered jailbreak.
I have to admit that the reason I’m yet to jailbreak my iPhone 4 running iOS 4.2.1 is simply due to the fact that there is currently no untethered jailbreak. I hate the though of my battery dying or my device crashing while I’m away from a computer that means I cannot boot it back up again.
It seems that this is another point to the Dev-Team that leaves Apple trailing far behind. If you haven’t done so already, will you jailbreak your iPhone 4, 3rd/4th-generation iPod Touch, or iPad if an untethered jailbreak is available? Let us know in the comments.
