As promised pod2g posted an update on his current jailbreaking progress and it looks like an untethered iPhone 4S jailbreak could be right around the corner. The A5 cache issue has been resolved and pod2g has received assistance from fellow iPhone hacker Saurik. Here is what pod2g wrote on his blog:

"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."

" 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!"

The good news is iPhone hacker pod2g is still working on his promised untethered iPhone 4S jailbreak. The bad news is he's having "processor cache" issues. Pod2g wrote on his blog:

"Here is the news of the 4S week-end.The untether fails right now because I'm having processor cache issues. I'm close, but I can't figure out what happens. It certainly has something to do with the Cortex-A9 cache management.I could sort it out quick, it's a matter of chance."

Pod2g excited the jailbreaking community when he successfully tested an untethered jailbreak on an iPod 4G and iPhone 4 running iOS 5.0.1 a few weeks ago. Currently their is no jailbreak for the iPhone 4S, but recent progress by pod2g and the Chronic Dev Team point to one being released soon. Pod2g promised another update on his progress tomorrow.

iPhone hacker pod2g just released a video showing his new untethered jailbreak for iOS 5. The video shows the new exploit working on an iPod Touch even after it has been powered down and turned back on. Pod2g tweeted that the jailbreak "will work on iOS 5.0.1" and that he plans to test it on an iPad 2 and iPhone 4S when he is ready. He also tweeted a link to his new blog which he says he'll update when he has more info.

Today I succeed in jailbreaking my iPod 3G. The exploit is user-land, rely on a user ROP payload and a kernel write anywhere exploit.

I can't give much details right now, but here are the next steps :
- upgrade the iPod 3G to iOS 5.0.1
- do the same on iPhone 4 / iOS 5.0.1
- then iPad 1 & iPod 4G

At every step, the exploit code needs certainly to be reworked, but I really don't know right now. Next, I'll return to the research for iPad 2 and iPhone 4S. I don't know if I gonna release first for other devices or not. I've to think about it. Feel free to give your opinion.
