Update on iOS 5.1 Jailbreak For New iPad, iPad 2, iPhone 4S


new iPad

On the day of the new iPad launch, the jailbreak community was on fire, first Stefan Esser and then iPhone Dev Team and chpwn + phoneixdev revealed that they had figured out a way to jailbreak the new iPad within hours of it going on sale.

Stefan Esser aka i0n1c was the only one to clarify that his 3rd generation iPad jailbreak was untethered.

He has just confirmed that his method is the only untethered jailbreak for iOS 5.1, which means iPhone Dev team and chpwn + phoneixdev’s methods are  tethered jailbreaks. (Update: phoenixdev has confirmed that his jailbreak is untethered, more details below.)

Why am I not surprised that iPhone blogs claim there are 3-4 untethered jailbreaks for iPad 3 around.

I guess the source of this misinformation is Redmod Pie – there is only one untethered jailbreak of iOS 5.1 so far.

There are actually more than 3 kernel exploits. iPhone Dev Team and @chpwn / @phoenixdev are sitting on their own kernel exploits for 5.1.

Untethering a JB however requires more trickery and additional userland bugs.

If someone is able to untether the latest device it is highly likely that he can untether all previous devices.

Here’s the video again (courtesy i0n1c) that shows an untethered jailbroken iPad 3rd generation:

i0n1c hasn’t still provided any ETA on when he plans to release an untethered jailbreak for iOS 5.1, which based on his tweets should support all iOS 5.1 compatible devices (which means the new iPad, iPad 2, iPad 1, iPhone 4S, iPhone 4, iPod touch 4G, iPod touch 3G).

Esser was credited for the untethered jailbreak for iOS 4.3.x and had given a presentation on iOS jailbreak techniques at Black Hat 2011 in Las Vegas last year.

Update 1:

phoenixdev has also confirmed that his jailbreak is untethered. He responded to i0n1c with the following tweet:

@i0n1c Not a kernel exploit, but yes I’m untethered. Wrap your mind around that now 😛

Update 2:

As some of you have pointed out, i0n1c has tweeted that he doesn’t plan to release the untethered jailbreak for iOS 5. Last time round, he had provided the details of the exploit for untethered jailbreak for iOS 4.3.x to the iPhone Dev team who had used it in Redsn0w. It doesn’t like it is going to happen this time round.

Update 3 (March 30th):

Some positive news after couple of weeks of silence, pod2G has tweeted that they’ve figured out some pieces of a userland jailbreak, and even if they end up figuring out the missing pieces they’ll will need weeks to release it to the public.
