Thread: 1.1.1 Question

    Default 1.1.1 Question
    My phone currently has 1.0.2 (1C28) version (Modem Firmware 03.14.08_G) and I want to upgrade to 1.1.1. However, I have already done the iPhone iUnlock which changed the Baseband, so the phone can be used with other service providers other than AT&T. What do I need to do to the phone to bring it back to the factory baseband before I upgrade? I don't want to to take the chance of bricking my phone. I use WIndows Vista.
