Hello. I know how to get into the programming mode on the Samsung A310 yet I dont know how to edit the settings. How would I do this? Also with the programming, is it possible for me to use NAM1 for normal service as programmed already and use NAM2 to lock my phone to different cellular providers to see their coverage areas which are CDMA as long as I have the SID + other info even though I wont be able to place calls and I take it this info can be obtained via FCC website such as SID, channels and whatnot?
