Unlock the phone by using the guides on this forum..

Im pretty sure the phone is unlock, i typed in the keypad a code (*#7465625#) and this is what it shows...Network Lock [OFF] Network Subset Lock [OFF] SP lock [OFF] CP lock [OFF]. So does this mean that my phone is unlocked? And I tried popping in a sim card from a active Straight Talk phone and it gives me "No Sim" message. I cannot change the APN settings because of this. I ordered a new AT&T compatable sim from Straight Talk so would that fix my problems?

Did you get a sim from straighttalksim.com? You'll need to.
