    My iPhone 4 no longer has 3g network. I am running AT&T, and I can make phone calls and send text messages but I cannot get internet. When I run Safari or any other web based application I get the "Could not activate cellular data network" message. My iPhone was once jail broken but no longer is. In the corner there is no 3g symbol next to AT&T. I have tried resetting data settings and restoring it but nothing works. Please help...

    Call at&t. They will likely have you reset the Network settings, or they may have an issue with your local tower.

    Since you don't say, I'm gonna ask some pretty obvious questions.
    Is 3G turned on in settings?
    What kind of restore did you do? From backup or new?
    Have you tried 3G from many different cell sites/towers?
    What happens when you turn 3G off, will the phone receive Edge?
    Has 3G worked since you restored from your JB
    Did 3G work when you were JB?
    You say that you reset "data settings". I'm gonna assume that you mean "reset network settings"

    I would take it to At&T, and get a new sim, then try a "Restore As New".
    If that doesn't do it, seems to me that everything points to a hardware problem.
