    Default [iPhone 3G] Official Unlock IMEI able to unlock any iPhone?

    This is mainly for the DevTeam because I don't have a clue how this works...

    I have a normal locked UK iPhone 3G and an unlocked Italian 3G.

    The phones firmware are the same - I restored them both with pwned software and they remain locked and unlocked respectively!

    I was wondering how iTunes knows which phone to unlock or lock?

    If it is because of the IMEI then would it be possible that if I could "change" the IMEI of the unlocked phone to the same as the locked phone then iTunes would unlock it?

    I realise that may not be possible or legal but I am just curious if that would work?

    FW 1.0.2--> iUnlock--> iPhoneSIMfree--> 1.1.1 --> 1.1.2--> Soft upgrade 1.1.3 --> 1.1.4 using signal.app
    iPhone UK 16GB
    FW 1.1.3 OOB --> 1.1.4 --> iPlus 1.2 unlocked!

    I think that, that's what happening with the belgian iphones, all iphone's send to belgium are registred in apple database with their IMEI number. when you activate the iphone, wherever you are, whatever the sim, iTunes reconize the IMEI from the phone, check where it was send to, and unlock the phone when the IMEI correspond to a valid IMEI in apple database ... hope you undersand

    So in theory if someone came up with an app that tricks iTunes into thinking the serial number and IMEI are that of a legitimate unlocked phone then it would unlock it?

    Obviously if hundreds of phones turned up all over the work with the same serial and IMEI then it would be obvious but for someone with an unlocked phone like me I could get away with it with 2 of them! if that is how it works and if such an app existed!?

    Correct or wrong?

    in theory you could be correct i think.. i dont know much about this stuff...what we need is to find out what exactly itunes does to the phone that makes it unlocked.. and then just try to reverse it and write an app that would do the same any iphone..but thats easier said than done..
    eh spinstorm.. i got a question for you.. did you click activate on the custom firmware for your unlocked iphone or not??..if you did not and let itunes activate it.. that makes sense y the phone is unlocked because itunes just actiates it and checks the imei and unlocks it.. but im curious if you try and restoring your unlocked iphone with a custom firmware and clicking activate and youtube.. i would lke to see if the phone is unlocked pernamently or itunes unlocks it everytime it has to get actiated

    I activated it through iTunes.

    However on an unlocked phone ANY SIM will activate as long as it fits in the phone (like all SIMS should!) then iTunes will activate it - no questions asked!

    I know from experience that if you activate using pwnagetool on the 3G that it DOES NOT aquire a signal.

    I am not sure if that is an intentional thing down to the fact that the 3G has not been unlocked yet or something else.

    I may give it a go when there is a reason to restore though.

    I can tell you that iTunes never at any point "told" me the phone was unlocked - even after restoring - it just IS unlocked!

    I thought of the same thing when the first gen iPhone came out, but since official unlock has been around for more than a year now (first gen also has official unlock version) and we haven't heard anything about it being an opportunity or learning point for software unlock, I guess it just doesn't bring anything to the Dev Team.

    Mine gets signal just find when activating using ptool. :/

    Just to add, I know older versions of ZiPhone could change the IMEI but it's not been updated for 2.0 and most probably never will be.

    Now, changing the IMEI is illegal and could land you in hot water if the network notice etc. They do keep a log of everytime your phone logs in and out of the network. So just make sure, that if you ever do change the IMEI on your locked phone to that of your unlocked phone - that the unlocked one has no sim card in it (and even better, switched off).
