Unlock test

[Fritziam]

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?

Install Ultrasn0w with Cydia for the unlock

[droop4]

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.
