JailbreakMe 3.0 To Jailbreak All iOS Devices From iPhone 3GS To iPad 2 On iOS 4.2.1 To iOS 4.3.3

JailbreakMe 3.0

Comex – developer of JailbreakMe – popular browser-based jailbreak tool who is expected to release a new version of the tool to jailbreak iPad 2 has revealed that he has reduced the time it will take to jailbreak an iOS device by using a unionfs approach instead of using the stashing approach that has been used by jailbreak tools.

He has also revealed that he plans to use this approach for the iPad 2, thus indicating that iPad 2 users will have to wait for some more time for the eagerly awaited JailbreakMe for iPad 2.

Comex has provided the following information about the performance improvements:

If you don’t know, the stashing approach jailbreaks have been using for years– Cydia’s “Reorganizing Filesystem”– involves moving some large directories from the small / partition into the large /var partition, then creating symlinks from the original to the new location. This both ensures that any additional stuff put in those directories by packages will end up in the /var partition, and frees up space on the / partition for files created outside of those directories. However, the process has some issues, like taking forever to do when you jailbreak (I am a bit fanatical about speed), pretty much requiring the jailbreak to reboot the system to ensure there aren’t any running applications pointing to the old files (ditto about speed, I want a jailbreak to not even require a respring, as in star, but since star used stashing, some obscure things could cause issues before a reboot), and seriously confusing the sandbox code in the kernel (because each application has a sandbox with a list of allowed filenames, but after the symlink has moved files, the filenames no longer match), requiring that code to be patched (it needs to be patched anyway these days because tweaks have to run under the sandboxes of the applications they’re hooking, but depend on accessing various directories; but it still feels good to get rid of a kludge).

With unionfs (which was saurik’s idea originally), new files are created in the /var partition, and merged with files in the corresponding directories in the / partition, so no files need to be moved, no descriptors are invalidated, and I think the sandbox code won’t notice what happened. It also opens the door for upgrading the base operating system without destroying the jailbreak files (although maybe iOS 5 delta updates will already allow this? I haven’t looked at them yet).

I’ve wanted to do this since literally a year ago (that’s the date of the nullfs checkin, since I was dumb and thought I wanted that instead of unionfs), but I never got around to making it work properly.

So, I just hope that I can get rid of the crashes my meddling with unionfs’s code have introduced, and fix it for the iPad 2 (my dumped copies of iPad 2 kernels do not include symbols; I wrote a small BinDiff-like tool to copy over symbols from a kernel for another device, but it’s not perfect) and that there aren’t any performance issues.

Comex has also revealed that the new version of JailbreakMe will support iOS 4.2.1 to iOS 4.3.3 to one of his followers on Twitter and MuscleNerd of iPhone Dev team has indicated it will support all iOS devices with the following tweet:

@itaiyz97 see @comex’s feed tonight for his huge spoilers 🙂 All devices from iPhone3GS through iPad2, iOS 4.2.1 to 4.3.3

That’s good news as JailbreakMe 2.0 for iOS 4.0.x was the mother of all jailbreaking solutions as it allowed users to jailbreak their iOS device using mobile Safari. Based on MuscleNerd’s tweet, we’re assuming that JailbreakMe 3.0 will support iPod touch 3G, iPod touch 4G, iPad 1, iPad 2, iPhone 3GS, iPhone 4 (GSM) and iPhone 4 (CDMA).

Comex hasn’t given any release date, but based on the update above it looks like it will take some more time.

As always, we’ll let you know as soon as there are any further updates, so stay tuned here at iPhone Hacks or join our Facebook Fan page or follow us on Twitter or subscribe to our RSS feed.

  • Zolk

    I know a lot of mainly ipad2 users are eagerly waiting for this, but as someone on a jailbroken, unlockable iphone3gs running ios4.3.3 already, I’m eagerly awaiting a successful untethered, unlockable (via preserved old baseband or whatever) ios5 (and the ios5 release itself, obviously!)

  • Matthew s

    Muscle turd and cockmex y dont yall clowns give a realese date? Y cause u like the attention u guys get from this.. Because yall are nerdy as shit and now u feel accepted u losers!

    • kiddowiddo

      You think they’re nerds do you? Well, listen dickhead, if it weren’t for what you call “nerds” there wouldn’t be all the technology and computers and super duper phones would there? And same goes for this, if it weren’t for these guys we couldn’t enjoy the privileges of a jailbroken phone, so before you post a fucking dumb comment, think about the stupid fool you are, what these guys do for us, and what you can’t fucking do for the world. Stupid mofo

      • fas

        Relax there. People will crib. Because no one likes waiting. What ever we say, does not change the release date.

      • Matthew s

        Are u stupid!! Jailbreaking is easy once you get the concept u dummy! Jus like everything else! Could i do it? Probably not! But they already jailbroke it like 3 or 4 monthes ago, they jus love the attention! I will take back my disrespectful comments on comex but musclenerd is a joke that loves the attention, if i could make a tweet and affect 300000 people i wouldnt leave off the attention like mn!

  • deano

    kiddowiddo, your a mouthy ball bag licker matthew is right these guys piss us all around

    how mant times does that freak musclenerd tweet telling us what he as done but it never turns out he talks bollocks, i would love meet him i would stick my iphone dopwn is throat

  • Knight

  • Dean

    Joshua hill knows fuck all to he just used limera1n in greenpoison another fact

    Because shatter never worked i know I was a tester

    So hacker go and take your bullshit elsewhere

    Comex you have skills….. Kid unlike these fuckers who use your and geohot expoilts and claim them as there own musclenerd, Joshua hill, and the rest of the devs

  • Doctor

    yeah fuk musclenerd hes done nothing ALL HAIL COMEX

  • Finally!¡!¡

  • deano

    finally what???????

    no release date

    and how many times in 3 years have we heard jail broken all devices or jail broken 4 life it never happens really because apple comes out with a new ios and it starts again

    but it wont stop people on here giving credit to the wrong guys or just talking bollocks like hacker musclenerds bitch i call him nowadays

    • Zang

      The devices are Jailbroken for life, what are you smoking this time Deano?

      There always seems to be a problem with you. All big talk and no action.

      You were a tester for shatter? Then why don’t you develop a new Jailbreak? As testers in the software world also know the code and report any bugs etc in the actual code.

      Or is that just a lie your saying? If not. Release the shatter code then, as if your telling the truth as an actual tester you would have had access to the code.

  • EJ

    We may not have a release date but we do have a solid deal that he comix is making a took and that it’s not a hoax that’s all I need

  • Ramiz khudafi

    Same shit I been hearing ipad3 isn’t Comin out till march 2012 hurry the fuck upguys cmon ill pay for it if you want just get it done!!!!!

  • deano

    shatter did not work you moron its no good and its not for me to release a teams expoilt working or not i know it does not stop musclenerd from doing it but hes a knob

    and the shatter code is on the net, took me 10 mins on goole to find it

    like ive said before do your research before you posting your crap

    quote by zang The devices are Jailbroken for life, what are you smoking this time Deano?

    ipad 2???????? enough said moron

  • hacker

    i could give you more links but im tired so use goggle fucking moron and the next time you post some shit think before you write and don’t come back until something hits you in the head cuz you don’t even make sense and you have the worse grammar your probably not even from this country who acts like there 10 years old and i got more important things to do then educate your stupid ass

  • deano

    hacker, your a complete noob you know fuck all about jailbreaking you just use redsn0w or pwnage and kiss musclenerds ass

    so please educate yourself little man try some reverse engineering yourself or try find a hole in the ios to expoilt

    but sadly you cant do shit???? can you
    thats why you creep on here kissing ass to people who dont do the hard work for themselves but fuck pigs like you still give them the credit

    i hate creepy pussy blokes like yourself the world would be a better place if knob heads like you were put in front of a wall and shot

    and how the hell did i halfwit like you pass a credit check to get your iphone in the first place

    dont worry little man i think musclenerd will tweet later sayin hes done something else which never happens but atleast you will feel happy

    now hacker piss off, you donkey ball bag licker and if you take that cock out your mouth when posting your bollocks it might make sence

  • hacker

    a reverse engineering would know grammer and why you always talking about Animal balls and cock what are you an animal pornstar who fucks in the zoo and i got better ideas then trying to find an exploit for you so go back to your donkey balls and pig balls and all the balls you can handle and what the hell does you know fuck all mean?its sound like you need to back to school and i dont know if you notice but everyone here think your rude and would all agree if you just hang yourself in the zoo with your family.

  • Jared619

    Can someone please help me?

    I have an iPhone 3GS and I used the previous jailbreakme to get to 4.0, I am on 05.13.04 baseband. This is all I have done to the iPhone, no unlocks, just the jailbreak.

    I understand that I have to get it to 4.3.3 to use jailbreakme 3.0, but how should I go about doing this?

    Should I just plug it into iTunes and update to latest? I don’t know if I should be concerned about iTunes updating the baseband or something.

    Thanks for your reply! I’m sure more people are in the same boat with me
