after upgrading iphone 3gs to ios5.1 i am getting "No SIM Card Installed" error
The phone is not even recogniced in itunes. It is giving me a prompt to "configure" and the phone goes through an activation process without any luck.
ATT saying it is an apple issue and Apple support is saying get a new SIM card if not get a new device as your device is out of warranty !!
😟 any help would be greatly appreciated.
iPhone 3GS, iOS 5.0.1
