  • Dev Team 1.1.1 Jailbreak
    cash edit: Read our Jailbreaking 1.1.1 on OSX Guide HERE
    Windows Guide HERE

    The Dev Team has now announced a 1.1.1 jailbreak method which allows for:
    • Downgrading to 1.0.2 (if necessary)
    • Preparing the iPhone for a jailbroken update
    • Performing a software update, leaving you with a jailbroken v1.1.1
    • Forcing v1.1.1 to mount read-write so you can access it
    • Installing SSH and BSD world
    • Activating with a Non-ATT SIM
    • Patching SpringBoard to allow third-party applications
    • Clean-up
    This does NOT allow you to unlock a 1.1.1 iPhone, and WILL NOT WORK ON AN UNLOCKED IPHONE. Again, if you have unlocked your iPhone, DO NOT DO THIS.

    Download here.

      Yes.

      I have not tested, but I am assuming yes, only with a valid AT&T account and SIM. I would add unlimited data, though, so you don't see any through-the-roof data charges.

      Will it be fully working with another provider if unlocked with IPSF? (I'm with Fido in Canada, NOT AT&T)

      You can use this method if you unlocked using the IPSF method.
      That's freakin great news! I suppose that means that this will be the preferred method for the 1.1.1 unlock...if the underlying hack is still sound...

      ok, my phone is on 1.0.2.
      it was unlocked using Anysim, I then followed the bbupdater/.eep process and Re-locked it, giving me a virgin iphone.
      I then unlocked it using IPSF.

      Am I safe to use this method?
      is there a way of checking the baseband to make sure it was repaired during the re-locking ?

      I am not sure, but I do not think so, since the upgrade to 1.1.1 breaks the unlock, although not the phone, when done on an IPSF'd phone.

      No, upgrading an IPSF'd 1.0.2 to 1.1.1 breaks the unlock, and you wind up with a LOCKED but working 1.1.1 iPhone.

      If you used AnySIM, your baseband HAS BEEN UPDATED, and you cannot use this method to jailbreak. Wait.

      but as I said, I followed the guide here to re-virginise the phone and undo the baseband modifications, is it still not safe?

      also in reply to someone above you just said "upgrading an IPSF'd 1.0.2 to 1.1.1 breaks the unlock"
      the IPSF website says it's unlocked after upgrade to 1.1.1 just needs re-activating.

      or am I wrong? sorry, and many thanks

      No guides which promise baseband "virginizing" actually work. Your baseband retains the modded code with all these methods so far.

      I'd like verification from someone who has actually done this on this one. From all the reports and posts I've read, IPSF'd 1.0.2 or before phones are fully LOCKED after updating to 1.1.1, and you can ONLY use the iPhone with AT&T then, until a new unlock method comes out. Yes, you WILL have to reactivate the phone, but using your AT&T account only.

      Correct me if I'm wrong, folks. I'm 99% sure that's the situation.

      I think we need someone to try to use this method on an IPSF unlocked phone to see if it will work with another provider. Keep in mind that in the worst case, you can simply downgrade back to 1.02 and the phone will still be working as before...

      I am fairly sure also that you would have to rerun the IPSF software after downgrading back to 1.0.2, and you will then have the new baseband that came with the 1.1.1 upgrade. So keep that in mind as well.

      Quoting from Iphonesimfree.com:
      September 28th, 2007:
      Q & A For iPhoneSimFree Users and 1.1.1 iPhone Update



      Seems there is a bit of confusion about our last post. Here are some of the most common questions, with some corresponding answers.

      Q. Why do you say it is unlocked if you can't activate a non AT&T sim?
      A. There is a difference between unlocking and activation. Unlocking is related to GSM standards and allowing a sim to be used on different carriers, and activation is something made up by apple to further restrict their users. After upgrading to 1.1.1 the radio of the phone is still unlocked, meaning it can still connect to other carriers, but apple requires the phone be activated to do so.

      Q. How do you know it is unlocked if you can't activate?
      A. There are several ways to know this. Firstly, the phone does not report "Incorrect SIM". Secondly the IMEI is correct. Thirdly if you bring up the field test, you can see the provider is not AT&T. And finally (and coolest of all), there are ways to actually call out and receive calls from the emergency call screen. If you can get the baseband to crash (we do it by calling some emergency numbers with no sim in place) and then insert the non AT&T sim, it can pick up a signal and calls (non-emergency) can be placed and received from the emergency call screen on the non AT&T carrier.

      Q. Why does all this matter, if I can't yet use a non AT&T sim?
      A. A few reasons. Firstly the phone can still be used by AT&T users after upgrade. Secondly, if apple has patched the methods used to perform the unlock, as long as an activation method is discovered, the phone will work perfectly on other carriers. With other unlocking solutions, if you were to upgrade the phone it would currently be a brick, and if apple has patched the methods to perform the unlock, it would also stay a brick forever..
