    Hello all,

    I recently got a used iphone 3g from someone. He had erased all data and he activated it for me.
    When i checked, it showed me
    Version: 3.1.3 (7E18)
    Firmware: 05.12.01

    After coming home, i accidently resetted all settings, and now its asking me to activate the phone with sim card. I dont have any sim card yet. Even iTunes doesnt recognize it and tells me to insert Sim card.
    The phone was originally from Fido, and I want to use it with Bell Mobility.
    Bell said that bring an unlocked phone and they can give me a sim card.

    So all i want to know is could i jailbreak and unlock an inactivated phone? Or do i have to call that person and tell him to activate the phone again as he has the original sim card..
    Hope to hear from you soon

    Thanks in advance!

    Try forecast by ih8sn0w. If it says Unlockable, then google around a bit.

    Looks like you cannot unlock it. You or your friend updated to the newest firmware and baseband.

    Just follow this procedure and check if it works, make sure iTunes is open before starting!:

    1. Hold the power and home button at the same time for 10 seconds.
    2. Release the power button and keep holding the home button.
    3. Your screen should be blank and iTunes should detect it in Recovery Mode..
    4. You can now downgrade/Restore.
