iOS Hacker Is One Step Closer To Jailbreaking The iPhone 4S

iOS hacker Pod2g, who has become increasingly famous over the last few weeks thanks to the progress he’s made on an untethered jailbreak for iOS 5, is one step closer to jailbreaking the iPhone 4S. Apple’s latest iPhone was tricky to hack thanks to its new dual-core A5 processor, but Pod2g reports the new chip “is not a problem anymore.”

In a new post on his blog, Pod2g announced his progress and thanked another hacker, Saurik, the brains behind Cydia, for helping him solve the puzzle:

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!

While an iPhone 4S jailbreak is still some time away, this is terrific progress, and it’s great news for iPhone 4S owners who are itching to hack their new device.

    At least until a mobile Quad Core comes out, then a three/five/eight core series.

    I really like this guy. He seems to have a lot of passion.

    Why don’t you launch a new website called Cult of Jailbreaker?  I couldn’t care less about jailbreakers.  They encourage and promote THEFT of iOS developers’ hard work.

    Spoken like a true uniformed sheep.  The jailbreak community provides significantly more legitimate features and options than what you’re parroting (minus the details, of course).  Some are so good that Apple even incorporated them into iOS 4 (multitasking) and iOS 5 (notifications & folders).  Also, once you start using SBSettings or InfiniFolders, you’ll wonder why these features are *still* not part of iOS.

    You have no idea what you’re talking about.  Most people in the “jailbreak” community do NOT steal apps from developers.  I pay for my apps both jailbroken and iOS approved.  I love some of the tweaks that are available on a jailbroken phone.  While theft is possible and there are those that do so, you can’t lump everyone into the same boat.  Do some research before posting drivel.

    i thought the piracy myth had been debunked already. I guess some people will never let it go. Anyways this is great news for those of us who like having options to customize our iPhones. Most Cydia tweaks make iOS much better.

    Please stop with the theft BS. If you really want to know what jailbreaking is about than try it out yourself. Otherwise stop insulting people and accusing them of being thieves.

    Wow, like most have stated already, most jailbreakers do not STEAL, I jailbreak because it gives me the freedom to what I want with my device, there are more tweaks and mods than anyone can ever install on 1 handset.   I for one have an iPhone 4S and cannot wait for my jailbreak!  Photoalbums plus, locktopus, sbsettings, mywi, just to name a few, are all legit apps that I have paid for through Cydia.    If your not jailbreaking your iDevice, all i gotta say is, YOUR LOSS.  Nobody elses.  Probably a good thing that you dont care about jailbreaking, you probably would be real annoyin in the forums trying to help your ignorant ass.  just my 2 cents.  Ciao

    Jailbreaking encourages and promotes piracy the same way that owning a computer encourages piracy.

  • Manuel Viramontes

    This is a website about Apple TECHNOLOGY! If you knew anything about the jail breaking community it gives you full access you modify and customize your device and allows you tweaks & mods that Apple does not include initially. Apple even acquires certain certain ideas from the jailbreakers! Even some hackers themselves have been hired by Apple to help come out with new versions of IOS! Know what you speak of before you start mouthing off buddy.

    Thank you for remaining blissfully uninformed and promoting the use of blanket generalizations. The world owes you no small credit.

    Anything I could say to properly represent the jailbreaking community and the concept itself has already been said and doesn’t need reiterating. You can go ahead and choose to remain ignorant, and I will take this opportunity to tell you so.

    We don’t need sheep like you to understand or approve.
