Untethered iOS 4.2.1 Jailbreak Confirmed!

Dev-team and Comex has confirmed that untethered iOS 4.2.1 jailbreak will be out before Christmas 2010. First MuscleNerd came up with a video demonstrating untethered iOS 4.2.1 jailbreak on iPod Touch 4G.

According to MuscleNerd, it’s a backup plan for untethered iOS 4.2.1 Jailbreak because comex is working on a more extensible one, but this method is also generalizable. This method Uses iOS 4.2 beta 3 SHSH blobs Cydia kept for you.

What is the meaning of UNTETHERED ?

ryanu December 9, 2010, 10:09 pm

Meaning that your device does not need to be connected to the computer to boot. Basically it means your i-device is independent of computer, and it can boot all by its lonesome self. Correct me if i’m wrong.

I want to make sure I’m reading this correctly, “*** This will jaibreak all iOS 4.2.1 devices UNTETHERED!” this includes iPod touch 3G?

dude010 December 10, 2010, 2:32 pm

What is so difficult to understand the meaning of “*** This will jaibreak all iOS 4.2.1 devices UNTETHERED!”

All means ALL including the iPAD, the iPod 3G etc. AAAAALL!!! πŸ™‚

So is it ok to upgrade from iphone 4 4.1 to 4.2.1?

Andro December 13, 2010, 7:36 am

i dont see anywhere in this article talking about iphone4, it’s been all about 3G,3GS, touch and iPad … they DO NOT WORK on unlock for iphone4, perhaps they just can’t unlock it but too shy to say it so

i believe that unlock for iphone4 on new baseband is just a myth, or it will never happen

iosmaniac December 13, 2010, 7:49 pm

there is no such thing as “NEVER”

Andro December 15, 2010, 7:44 am

ok, there’s no such this as “never”, but “gonna take forever”

oudom December 13, 2010, 8:52 am
