Data no longer working over 3G?

[Strategy]

I'm not sure what I did but my data no longer works over 3G. If I change it to EDGE or wifi it works fine. I've rebooted my phone twice now, switched 3G on/off and nothing is working. I'm not sure what else to try, phone is jailbroken but it's been working fine for at least 3 weeks.

You should restore and rejailbreak it, and see if that fixes the problem.

Did a reset network settings and that fixed it. I forgot about that setting.

Mine did the same thing a few days ago.
Weird. I did a hard reset and toggled airplane mode a few times.
Seemed to have fixed now.
