    Is it already JB?
    Go into settings,general/about and let us know what modem firmware version you're on.
    Do you see a cydia icon?

    You should go into cydia and download blacksn0w it should unlock your phone. Turn 3G off as T-Mobiles 3G bands are not supported by the iPhone. Then insert you T-Mobile sim.
