Mobile data not working after upgrading to iOS 4

[slowpoke]

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 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.

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.

How certain are you that you didn't jailbreak?

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