iOS 5.0.1 Build 9A406 Fixed The iPhone 4S Invalid SIM Error?
It came as a surprise for many that Apple quietly released a second version of iOS 5.0.1 and only for the iPhone 4S. It turns out that the update wasn’t an accident. This new Build 9A406 was intended to deal with certain complaints from customers where the iPhone 4S would not detect the SIM Card.
Unfortunately, not everything has been perfect. There are mixed results so far in which certain customers haven’t seen any more issues, and others have. Obviously it’s a little too early for those that do see improvements to confirm if they won’t have any, but so far it seems that Apple hasn’t had the best time ever in fixing problems with their recent iOS updates.
Are you having any problem with your device after the update? Leave us a comment down bellow.
