    Default Having trouble upgrading jailbroken iPhone to 3.0
    Recently i was trying to upgrade my iPhone to the 3.0 software by doing a restore. Every time i try i get the 1602 error and the phone goes into the screen to connect phone to itunes and the computer stops recognizing the phone. I then connected the phone to another computer and had to restore back to 2.2.1. I am not sure what to do, how can i update my phone to 3.0?

    Thank you

    Perform your jailbreaking with the computer that you use to restore to 2.2.1.
    1. Clean install by restoring (DFU) to Apple firmware iPhone 3.0.
    2. Jailbreak

    Try a DFU restore to 3.0. If you have another computer why didn't you just restore to 3.0 on that one?
