  • How's the Untethered iOS 5 Jailbreak Coming Along With the iPhone 4S?

    Pod2G is working hard.

    Remember Pod2g? He's the guy that made a successful iPhone 4 and iPod touch 4G unethered jailbreak for iOS 5 just within the past couple of weeks. Now, as he promised, he is working hard to get the iPhone 4S and iPad 2 untethered so that the rest of us using newer devices can be happy too. The untethered jailbreak is the one that you can use even after rebooting your iPhone. Whilst in a tethered jailbreak, you cannot reboot your iPhone at all until you connect to a computer and use software to reboot it. There is a semi-tethered option which allows tethered jailbreak users to reboot their iPhone except without and jailbreak features - only the functionality of stock iOS features.

    Pod2g is shifting into top gear and attempting an untethered jailbreak for the iPhone 4S completely disregarding the tethered jailbreak; but that's what we wanted anyhow so there aren't any complaints. What we know about Pod2G's jailbreak so far is that it will be untethered for A4 devices such as the iPhone 4 and iPod touch 4G running either iOS 5.0 or iOS 5.0.1. At this point in time the iPhone 4S doesn't have any jailbreak; not even a god-given tethered jailbreak which most of us would give an arm to have on our iPhone 4S at the very least right now. Pod2g is on the case though.

    So what's the update for the iPhone 4S? Well, if you refer to the image above, you can see that Pod2g has reported on his progress for the iPhone 4S untethered jailbreak. In case the image doesn't load for you, the message reads:

    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!
    So what does this mean exactly? It means that Pod2g is ever so closer to breaking the seal of the iPhone 4S. He received an iPhone 4S thanks to generous donations - he also got himself an iPad 2 to test with. He mentioned that he is having processor cache issues while trying to work with the untethered jailbreak, however one thing that he left blatantly unclear is whether or not he has a working tethered jailbreak for the iPhone 4S. While many of us would prefer the untethered jailbreak, there have been a myriad of comments here on Modmyi from iPhone 4S owners saying that they would at least settle for a tethered jailbreak until the untethered jailbreak could come out. After all, it's better than nothing.

    The cache issue could be very large or very small. It could be fixed in a matter of hours, or as Pod2g explained, maybe days or weeks. The problem depends on chance. It depends on whether or not Pod2g finds the problem or not, albeit he did promise us that he would inform us of his progress again tomorrow so that we can see how it went after today with his processor cache issue. The processor cache issue is keeping the jailbreak from being untethered at this moment in time and hopefully if he can bypass that issue we can have an untethered jailbreak for all devices up to date.

    Are you hyped about the iPhone 4S untethered jailbreak? Tell us your thoughts in the comments.

      No more cache issues
      Darn picky internet blocker at work won't let me read. So he's fixed the issue with the cache? Great news. Hopefully a untethered jailbreak in our very near future

      Here ya go, straight from 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.

      For the tech guys, here is a link explaining issues related to self modifying code ( or code patching ) on the ARM platform : Caches and Self-Modifying Code - ARM Community

      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!

      I think it's best to just wait until the untethered is ready because if pod2g comes out with a tethered first wouldn't apple see the holes he used and come out with a update to close the holes?

      Can ANYBODY verify either one of those supposed jailbreaks? I'd think if it was real we'd def be seeing a lot more of I advertising for it. Seems shady to me.

      No need to verify. You can just look at the names and the source and tell it is fake.

      They just came out of the blue? Doubt it! I'd only believe the reputable coders, dunno who these guys are.

      Processor cache issues ?
      He means cache issues with the A5 processor right ? Not his PC having issue with cache ???

      if you do get an intel processor
