    Hello,

    Now I am a bit of a noob when it comes to the Iphone scene, so please bear with me.

    I just recently purchased an Iphone for a steal on ebay. Its an Iphone 4 on version 5.0.1 (9A405) with firmware (baseband) of 4.11.08.

    From searching online, I think the baseband is a concern for me. Is there a way for me to downgrade that?

    What steps should I take to unlock it? Its currently on At&t and I want to use it on T-mobile.

    Thanks

    first you would need to jailbreak and run ultrasn0w but from what ultrasn0w says it only does 1.59.00, 4.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00

    and im not sure if you can go to 06.15.00 but if you can dont do it!!!!
