I followed the unlocked instruction from AT&T to restore my 3GS iPhone from factory settings.  After completing restoring, follow the steps to set up the phone and stuck at activation screen.  I inserted AT&T SIM card and connected to iTune but still failed to activate with following error message on iTune:


"There is no SIM card installed in the iphone you are attempting to activate.  Please disconnect and insert a SIM card in the iPhone."


I have retry several times (including disconnect and reinsert the sim) but no luck.  Any help would be much appreciated.


iPhone 3GS, iOS 4.3.3
