This is most likely the problem. It is an older AT&T sim, with just the globe on it. So even if the phone was unlocked, the SIM would still not work?
I wish all of CS would get on the same page. It is one thing if they cannot provide me with the unlock code if I dont meet their criteria (which I believe I do) but to tell me that it is illegal and there are laws against such thing seems terrible. I don't know how they get away feeding false information to so many people.
