SIM Network Unlock PIN on Cyanogenmod
Hello- I have a Samsung Infuse (Galaxy S Android) which used to be on AT&T. I rooted it and have been using Cyanogenmod ROMs as a Straight Talk Wireless customer with no problems. I recently got a t-Mobile prepaid SIM card. But when I install it in the phone I get the "SIM network unlock PIN" message. T-mobile is support is telling me its because my phone was never unlocked.
So my question is about what are my options to get this going? Can someone give me some ideas. Admittedly, I only know enough to be dangerous, so details on what to do would be great.
