iOS 4.3.1 Untethered Jailbreaks in the Works, iPad 2 Support Unclear

Since the launch of iOS 4.3 on March 10, the only tools able to jailbreak iOS-powered devices have been PwnageTool (for Mac) and sn0wbreeze (for Windows). While these tools will do the trick, they’re tethered, and require users to plug their devices to their computers every time they need to be restarted, or simply when they run out of battery.

While full, untethered jailbreak methods are not available just yet, recent findings seem to indicate that they are finally close to being released.

iPhone security expert Stefan Esser (aka xpl0n1c) managed to find a new exploit that could be used to jailbreak devices running iOS 4.3.1, and earlier today, Esser posted a video on YouTube to showcase the end result: his jailbroken fourth generation iPod touch running iOS 4.3.1 is able to boot without being tethered.

Esser does not build jailbreaks, so he patched sn0wbreeze to showcase his exploit instead. According to the security expert:

I repeatedly stated that I will not release a jailbreak tool – I will only give out the untether. I did not try yet, but if it is feasible the untether could be a cydia package. [...] While the vulnerability I use is in the iPad 2 kernel my untether will NOT SUPPORT the iPad 2, because there is no way to install it there (bootrom exploits fixed). – however Comex is working on that part.

Esser also mentions that while his exploit could be used in upcoming first generation iPad jailbreaks, the method will not work with the iPad 2, as Apple made significant changes to the device’s bootrom.

Apple built extra fail-safes within the device, and even when new exploits are found, Apple’s engineers patch them right away. For instance, Comex, the hacker behind jailbreakme, confirmed earlier today that the exploit he was planning to use for an upcoming iPad 2 jailbreak has already been patched by Apple via the iOS 4.3.1 update.

    Wait, does That means he will release it for 4.3?! Why hold out?!?!?!

    • joey

      More testing has to be done before they can put it out. You dont want a fail jailbreak do you?

  • NS

    Why is it that until now there is no iOS 4.3 Jailbreak for ipad 2?

    We are not interested in iOS 4.3.1 Jailbreak at the moment for iPad 2.

    I don’t understand why Comex is not releasing the knowledge how to JB i0S 4.3 to other developers when exploit was already patched.

    Interesting, he is keeping things for apparent no reason.

    People are so ungratefull. Do yo have any idea how hard this stuff is?? if i gave up so much of my time to do this, youd have to pay me to release it! just let them do thier thing, be patient and be gratefull :) i’m just as anxious as the next guy but it will be worth the wait i’m sure.

    Im not complaining about the untethered jailbreak, Im talking about his aptitude, he was saying on twitter that all his followers that ask him for the untethered jailbreakare all of them stupid. He made his apha, beta, gamma or whatever video about the untethered jailbreak and told everybody hey I got the untethered jailbreak, what he got to expect, of course everybody are going to ask him. I think If somebody have the jailbreak in alpha or whatever status that is not complete, dont tell nobody, keep it for yourself until you got it working. Dont try to look for attention saying or making a video about that you have the untethered jailbreak then later cry and insult or talk about your followers, because everybody is asking you. I really appreciate the help of you all devs and your hard work and I agree that it need to be released when is done. But again his aptitude stink.

    Here is one of his last twits:
    I don’t care if they can read my tweets. I just don’t want to read their replies.
    The block follower feature of twitter is awesome.
