    I have an old iPhone 3GS which is carrier unlocked. I'm currently running iOS 5.1.1. and it's not recognizing any of my SIM cards. Then again I know my carrier might have restricted my SIM card to work with my current phone.

    Does anyone know how I can check if my iPhone is for sure carrier unlocked?
