I upgraded the software of my iPhone 4s to 5.1.1, immediately after the upgrade it no longer detects my sim card. Tried reinserting the sim as well. Please advice - Deepak


iPhone 4S, iOS 5.1.1

    Try a different SIM card or one from a supported carrier.

    This usually means that the phone was unlocked by unauthorized means - by hacking or jailbreaking. If this is the case you cannot get help in an Apple hosted forum. Google is your friend.
