    Hi,

    I upgraded my 3G to iOS 4 and jailbroke it the other day. Everything works fine except data — whenever I try using the internet over 3G, nothing happens. Every app I try is unable to connect to the web. Calls and SMS still work fine.

    Is there a way to either a) revert to 3.1.2, or b) get data working on iOS 4?

    Cheers.

    Try reseting your network services..
    Settings > general > reset > reset network settings

    If that doesn't work.. Try turning your phone off for a min or 2.. And then turn it back on

    Make sure your bill is paid...

    Same Problem here

    I'm having the same problem (although I didn't jailbreak and I've got a 3Gs). Everything is working great except for data.

    Did you figure out the problem? Please tell me you found a solution as I tried the suggestion of resetting the network settings with no change.

    I previously had it jailbroken... is that what you are talking about? I didn't try any jailbreak after upgrading to iOS 4.
