Jailbreak For A5 iOS Devices Released 169

tlhIngan writes "It certainly took long enough, but the untethered jailbreak for Apple's A5 based iOS devices (iPad 2, iPhone 4s) has been released (official site, struggling due to traffic). It's currently only available for OS X, though ports of it to Windows are forthcoming."

Jailbreak For A5 iOS Devices Released

Comments Filter:
  • If Apple really wanted to stop jailbreaking, they'd just have to issue a required iOS update that patches the hole and cut off access for the older release, They don't do that. Instead, they allow the jailbreaks to happen and learn from what they develop such as teathering going from non-existent to paid to included.

    I do not expect that anybody has done this yet, but it might be possible.., right?

    It's great that they managed to extend the Corona jailbreak to the iPhone 4S. But unfortunately, very soon all their hard work will be rendered useless once iOS 5.1 hits release. As 5.1 is already in the beta-testing stage, there's only a window of a few weeks before it drops. Unlike iOS 4 and below, there is currently no way to downgrade any iPhone to an earlier version of iOS5. The SHSH method does not work anymore because of something new on Apple's end (I believe involving something called an "AP Ticket" but I honestly haven't looked into it very deeply).

    The point is, if you want to make use of this jailbreak, you must go to iOS 5.0.1 RIGHT NOW and jailbreak or you won't get another chance until 5.1 is hacked, which is of course never guaranteed.
    • you must go to iOS 5.0.1 RIGHT NOW and jailbreak or you won't get another chance until 5.1 is hacked

      You could also keep 5.0.1 for as long as necessary, reject the 5.1 upgrade, and jailbreak when you wish. No hurry.

      • The problem is that if you install something that makes your phone unstable, and need a restore, you will also lose your jailbreak when you restore. This wasn't true in previous jailbreaks.

          As I replied before you can restore as many times as you like with pre-A5 devices like the iPhone 4, even in iOS5. Just a bit of a new procedure.
          • Pre-A5 isn't what this news item or Absinthe is all about. The news item is about the A5 devices, which it will not be possible to downgrade once iOS 5.1 is made live. Yes, you can downgrade and untether A4 devices, but that is old news from December.

            So one mistake and your jailbreak is gone for good, probably.

            There isn't any guarantee that this will be remedied but I believe the jailbreakers make a living out of donations and expensive tweaks and such, and so they will eventually release some sort of tool

    • You can still downgrade to pre-iOS 5 releases if you have SHSH blobs saved for those revisions. Downgrading has been rendered "impossible" because the APticket used to verify ipsw's is now generated randomly instead of being solely comprised of data from the phone's ECID and firmware version.

      Actually for any of the pre-A5 devices this is not true. They have figured out a way to save the ticket AND shsh blobs and stitch them into your firmware file so you can flash back to it any time you'd like.

      A5 devices do not have any bootrom level exploits though so this is not possible. You basically have to get 5.0.1 going now before 5.1 comes out. If not you will be stuck with 5.1.

      BTW A5 devices are iPad 2 and iPhone 4S

    but goddamn do news posts like this make me â(TM)¥ my Galaxy S2, I owned 3 iphones, never again - EVER.

  • ... is exactly why you can't meaningfully compare jailbreak on Android devices that's there by design (e.g. Nexus, or most Samsung phones) to one on iOS where, every time there's an OS update, you have to wait and hope that someone will find an exploit to squeeze through.

  • If you have the latest 4.11.08 baseband, there is (to the best of my knowledge) no way to un-SIMlock it.

    My wife is travelling in Australia and China and wanted to use her iPhone there. Rooting and unlocking my Samsung Galaxy S took about 10 minutes, but there is no way to unlock the iPhone 4 if you upgraded to iOS 5. We could have paid Rogers (Canada) $60 to do it, but we didn't think of it until we left for Australia and it was cheaper to just buy a cheap nokia prepaid burn phone and then only use her
