I'm going to unlock my 1.1.4 8GB iPhone with iLiberty. I want to use a non-AT&T SIM with it. I currently have the phone legitimately activated with AT&T. When I use iLiberty, do I take out this SIM before the unlock and do it with no SIM in there? What do I do about the SIM cards during the process? Thanks in advance for your help!
