I decided to cop-out and go the easy route... called sprint, they asked some security questions (3 of them) and unlocked my device.

Only sucky thing is i can not unlock another phone within 12 months...

I have a Sprint M8, rooted, s-off, the works. I've done the SIM unlock but wondering why I can't connect either to AT&T or T-Mobile when I select GSM/UMTS Only in Preferred Network Mode? Or maybe that only works if I have an AT&T/T-Mobile SIM card? Just trying to figure out how unlocking the SIM card would benefit me, or not.
