iOS 5 Untethered Jailbreak: Pod2g Solves A5 Cache Problem

The progress for the French hacker known as pod2g continues with iOS 5 untethered jailbreak.

Keeping those watching closely and waiting for the release of a jailbreaksolution updated in his blog -- pod2g's iOS blog, a blog talking about iOS security research -- he posted Tuesday that A5 cache troubles have been solved.

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!

The comments from followers have quickly poured in, with many patting him on the back with others asking when they can expect a solution release.

perfect!!!! you are truly the best. when can we get our hands on the new untethered jailbreak? wrote user dannylall.

Good job man. Thanks a lot. Glad to see you were able to persevere through the exhaustion of trial and error. I too do computer work and that's the number one problem lol not wanting to take a break when you desperately just want to figure the shit out! Glad you did tho

Others, though, seems to want to know if they can update to Apple's 5.0.1 yet, since pod2g had told them recently to hold off on the update, since he's trying to crack 5.0.

;ord have mercy!! Is it safe to update to 5.0.1 before we miss it!! You told us to stay at 5.0.... Do we update now?'!!!????

4S 5.0, can we become 4S 5.0.1?????? !!!
