    Just upgraded my iPhone 4S to v5.0.1 over the air and upon reboot, received a message: NO SIM INSTALLED.

    I called Apple support and this is what I did:

    - powered off iPhone

    - removed SIM card and then reinserted

    - powered phone back on

    All is good now.

    That is the first time it has happened, so it kinda freaked me out... but hopefully this helps others if you encounter it.

    That certainly didn't work for me. I had to plug into iTunes and do a full restore to get the phone back in order.
