Hello,
i get the message "Unkown SIM status" on my previously locked to T-Mobile, unlocked device. how can i check if it was really unlocked?
The person who mailed me the device informed me he had it working with cingular a few minutes before mailing it to me. i tried to Fide SIMs so far.

Any help is appreciated.

I'm hoping to get an answer. i got someone to call t-mobile and get a new unlocking code in case it was not really unlocked.
but i'de appreciate the help
