Thread: iPhone 3GS 4.0.1 activation issue

  1. #1
    Default iPhone 3GS 4.0.1 activation issue
    I have a jailbroken iPhone 3GS. Upgraded it to official 4.0.1..then used to jb, ultrasn0w to unlock..everything was ok..until a friend came to me and restored the iPhone to the 4.0.1 from iTunes. Now the phone says it needs to be activated and I do not have the original sim..I don't even know what network was the original sim.

    What are my choices? Besides the phonebook card...which i don't have

    tnx in advance

    note: i tried downgrading to 3.1.2...itunes said the phone is not eligible for this upgrade...i also tried to install a custom 4.0 via pwntool...itunes gives error all out of ideeas

    You can check the carrier model from here :
    iPhone Carrier List – Model Numbers|TGIL, Inc
    If your iphone comes from Canada, you will have a little problem. There are 3 carriers in Canada that uses Iphone. All have the same model, the only difference , it is locked to each individual carrier.
    I suggest you get the official sim card after checking where your iphone comes from. This is your only way out.
    If you activate with phonebook sim card, you might have to patch the Lockdown file to ensure it is unlocked for all GSM.
    If you don't have 3.1.2 shsh blogs, then you can't downgrade in order to hactivate your iphone.

    Download tinyUmbrella and then check whether your shsh is saved with cydia. If not, am sorry you can't downgrade to 3.1.2. Use this link-
