    I've installed ios5 on my iphone 3gs.
    the previous software was 3.1.3
    but after ive installed ios5 & restarted my phont in order to activate it, the message appeared as below:

    The SIM Card Inserted does not appear to be supported.

    What should i do?

    Was the phone jailbroken under 3.1.3?

    Who is your carrier?
