My phone was SIM unlocked and I have been traveling with no issues. Simply swap the SIM card and GO. I did a restore becuase I am selling it and now I get a error message that says " Not a valid ATT Sim Card". When I put a valid ATT iphone SIM I have to activate and it works.

I can now not SIM unlock it using the same method (GUI). Is it possible that they pushed somthing in with the ilife updates ?
