The iPhone 4s untethered jailbreak has been achieved

The iPhone 4s has never had an untethered jailbreak. In fact there hasn’t really been any jailbreak for the iPhone 4s since we have first seen it about 2 months ago. Now there is going to be not only an iPhone 4s jailbreak but it will also be untethered. Even though they have cracked the problem for the A5 we won’t likely see this anytime soon so don’t get your hopes up. Most likely after Christmas. pod2G has cracked it and here is the official statement:

OK, figured it out, the A5 cache is not a problem anymore. I sorted it out by doing the untether in a single thread and by flushing all the dcache then all the icache in a row at a strategical point of the process. It took me like a hundred of tests to find the key. Hard for the nerves. For the tech guys, here is a link explaining issues related to self modifying code ( or code patching ) on the ARM platform : http://blogs.arm.com/software-enablement/141-caches-and-self-modifying-code/

Another news : I discussed with @saurik today about the launchd boot process, and he’s found one missing piece of the puzzle I needed to have a perfectly stable jailbreak. He’s definitly one of the best iOS gurus out there. Thank you saurik!

Good work guys. I can’t wait to see the tool for this.

iPhone 4S Unlock is in the works!

If you have an iPhone 4S and you need to unlock then you may be able to soon! According to musclenerd (@musclenerd -twitter) a member of the iPhone Dev-Team they have a unlock in the works! The iPhone 4S is the only iPhone that can’t currently be unlocked with ultrasnow or really anything for that matter. Here is the statement that musclenerd made

Crazy Thanksgiving weekeend! Very Promising 4S unlock is in the works (Not the i4, just the 4S… that’s the crazy part)

Above is the image that was posted along with the tweet. However let us not forget we need a jailbreak for the 4S before we can actually unlock the phone itself. The jailbreak should be coming soon along with the unlock.
