  • 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.

      can some please go into detail on how to execute the symlink. its this part in the read me:


      mv /var/root/Media /var/root/Media.old
      ln -s / /var/root/Media

      How do i "execute" this. This is the part that is most confusing, the rest of the process seems fairly simple....

      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..
      Therefore, shouldn't this method allow IPSF unlocked phones to be upgraded to 1.1.1 and work 100% with a NON-AT&T provider?

      thats what I thought.
      sadly though I used anysim, relocked then used IPSF, so I don't want to test this till I know if my baseband is modified or was fixed when I re-locked

      It seems to point to that. Anyone want to give it a try?

      As I have said before to you, your baseband was modded, so you currently cannot use this method.

      Yes. You may have to re-run IPSF, but I don't think so.

      Follow the instructions in the readme in the file linked to in the first post, and yes, if you have not unlocked, you can do this.

      No longer than half an hour.

      Hey All
      Sorry if this has already been asked but bit slow over here in Aussie land, and internet not displaying full forums properly.
      I've ordered an iphone from apple which will have the 1.1.1 firmware.
      Can I open the box, use this new patch method, and end up with an unlocked iphone (so I can use it as aphone as well)? Don't care if it's 1.0.2 or 1.1.1, just as long as I can use my sim in it.
      Thanks and Apologies again.

      I'm lost at step 6, what program am I using to connect to the phone and update the springboard?

      My first attempt also let me with a 300 meg iphone. I restored 1.1.1 back and now have my 8 gigs again. But I had rw access and all seemed to be ok, I just didn't know how to finish past step 6.

      Maybe I'll wait for a better step by step.

      whats the worst case scenario if someone was to run this on a 1.0.2 Anysim unlocked phone?
      permanent brick or just re-locked?

      Not that I'm gonna try it, but I get the feeling many will



      -------------



      Renzo - no, this is a jailbreak/activation, not an unlock.

      this will let you open up 1.1.1 (either a new 1.1.1 phone or upgrade a 1.0.2 phone)
      it will jailbreak it (for 3rd party apps) and it will activate it, but it won't unlock it.
      so you'll have a 1.1.1 ipod with wifi e.c.t.

      though looking at iphonesimfree.com you could use their unlock method on 1.1.1 but it's not been tested.

      ....at least this is my understanding of it all.

      Hi arcsbite

      See step 5 in the instructions provided - 'Activating with a Non-ATT Sim'

      This is why I was confused.. but I assume it's just not 'unlocked' as stated..

      Thanks
