    I unlocked to 6.15.04 from 5.15.04.
    Is there any way I can test it with my T-Mo sim, or is the sim ESN assigned; and I'd therefore need a new sim.
    Or is there some other way to test that all is well other then Settings/General/About/Baseband(modem) version?

    Yes! Go to cydia and search for "ultrasn0w" once installed you should be able to use your tmobile sim card

    Ps what device are you using?

    Be sure and go into settings - general - network and turn 3G to OFF.

    If you put in an unused foreign sim and it says searching and then no service, it means you are unlocked.
