SIM Not Valid after iOS 6.0.1 update
Hello All,
My iPhone 5 (AT&T) is unusable with the below error message after restoring it in iTunes to upgrade to iOS 6.0.1. I recieve the below error message "SIM Not Valid". My phone has never been jail broken and has the AT&T SIM card it came with. This phone has already been replaced once because of a hardware problem with the 1st phone I received.
Does anyone have any suggestions? I really don't want to waste time at the Apple Store again and this is my only phone, so I would like to get it up and running ASAP.
Thanks.
iPhone 5, iOS 6
