Update on the Untethered Jailbreak for the iPhone 4S
#1

Hello.
Here are 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.
I'll report you my progress tomorrow.
BTW: I removed (sorry) the greetings messages so that only articles related to the jailbreak remain in the main page. AFAIK Blogger don't have the option to move or fusion messages while keeping the comments.
Ciao!

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...modifying-code/
UPDATE: 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!
Update 5---
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.

PigPox. I really appreciate the update. Good luck with the cache issue!
Pod2G is the hacker/cracker working on the JB. PigPox is just the reporter avenue.

y he dosnt release the iphone 4 jailbrake
Because it's not ready, it's still being tested, and it'll get released when it's ready for the masses.
You want it faster, how about YOU do some coding and write the jailbreak, then release it?

^ yeah and it's still tethered. Read things first.
yeah but you can make it semi-tethered for the, I'm pretty sure the devs have a really good reason not to release the untethered jb as yet.

Wow Im always amazed by those that expect things to happen on their time opposed to the guys that spend COUNT.LESS hours working on this for us for FREE!!!yeah but you can make it semi-tethered for the, I'm pretty sure the devs have a really good reason not to release the untethered jb as yet.
I'm thinking the really good reason is because maybe they are going to wait for apple to drop 5.1 so they can't patch the exploit they found that will allow us to JB all device hence throwing their VERY hard work out the window? What do ya think good idea? I think it's a pretty strong reason why it's not and won't be released until 5.1 drops!!!!

but I can't stop asking my self, if Geohot was still in the scene, how could he take to jailbreak these A5 CPU with a boot-rom level exploits!!

What I would be really interested in was the compatibility of pod2g's JB with 5.1 Beta1/2... I guess he's not gonna give away any hints about that, because he's quite paranoid about possible leaks and clues that would help Apple to pin his exploit down (at least he said so himself). I think he should take the risk and wait for the 5.1 release with the hopefully fixed battery issue if it was compatible so far.
Otherwise we'd have a perfect JB for an flawed iOS version and the hopefully fixed iOS5.1 would most certainly be patched.
So it all comes down who this JB should work for - the average iPhone user who wants an 1-Click-JB aka. the masses, or the average Xsellize user that has his Blobs and SHSHs saved and can revert to 5.0.1 if it's really the last working version this JB is compatible with.
I go with the waiting. And that's coming from someone that sits on 2 brand new not even unboxed iPad2... (Can't open or Blob-save them 'cause they are presents!!! ;-() So pleeeease Apple, don't close the 5.0.1 window before the 24th ;-) And please Pod2g, be a good Santa!!!
EDIT: BAM, in your face! http://pod2g-ios.blogspot.com/ Can you smell it?! ;-)
