what are the possible issues if Iphone does not seem to detect the Sim card? It says No Sim...

THe problem arises after a software update due to the following problem.

Contact name does not appear if dialing without using area code. Previously, when i dial without the area code, the name will appear after keying in the last digit. However, out of sudden, that feature seems to disappear, and i realised that the name appears only after i dial with the area code.

So, i decided to do a firmware update. However, after the update, the iphone is unable to detect my Sim card.. Can someone give some advice on this?

MacBook, Mac OS X (10.5.4)

    1. Remove the SIM card. Insert the SIM ejector tool or the end of a small paper clip into the hole on the SIM tray. Press firmly and push it straight in until the tray pops out.
    2. Verify the SIM card is not damaged or dirty.
    3. Reinstall the SIM card.
    4. Turn the phone off and back on.
    5. Wait approximately two minutes, then see if the iPhone detects the SIM card and if it will register on the network.
    6. If that doesn't work, try another SIM card, if possible, to see if it is detected.

    If that doesn't work, contact an apple store, or if you have apple care, call them.

    Your profile indicates you are running 10.5.4.

    Download and install the 10.5.8 combo update to bring your system software up to date.


    After any installations, repair disk permissions.

    Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
