http://www.reddit.com/r/jailbreak/comments/nirbi/pod2gs_update_on_4s_jailbreak_he_is_getting_closer/ It looks like any day now and we are free from the constraints of AAPL's vision of how our (their?) product should operate. Finally, and gratefully. quote: "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!" ps: yes, this is a new thread. if it's repeated elsewhere, I apologize...just wanted a very clear thread announcing this excellent news as sometimes it's difficult to find updates in older threads.
