It looks like the caching issues that jailbreak guru pod2g was facing are now a thing of the past.
Just a while ago, the iPhone hacker updated his blog acknowledging that he had solved the the A5 chip cache issue, which means we are even closer to the reality of an untethered iPhone 4S jailbreak.
pod2g also touched on a few other points of interest regarding the much anticipated release…
Per pod2g:
No more cache troubles
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!
So not only was the caching issue solved, but another one of the lingering issues hindering a stable untether was solved as well.
Folks, we’re getting the impression that an iPhone 4S untethered jailbreak is making its strides into the home stretch.
We’ll have more news as it breaks. Stay with us.
