    I have AT&T and my data has not been working since I upgraded to iOS 4 yesterday. MMS, Internet, etc doesn't work. I have called AT&T and they don't know why and can't offer any solution. Anyone else having this problem?

    I have tried restoring my phone, resetting the network settings, and AT&T tried unregistering and re-registering my phone but still no data.

    Check your APN, the field is empty after upgrading to iOS4.
    Network -> Mobile Data -> APN

    I don't have a Mobile Data option on the Network screen.

    This works to restore data, but I still don't have MMS.

    Ended up restoring phone as a new device to fix it. Everything works fine now.
