hey guys,
for over two months now, my phones does not want to connect to the 3g, even in places where it used to (ie, my house). I have tried using the service menu, different apps, the network options, and have looked high and low but all the threads I've found end without an answer.

Right now i have,
2.2
Baseband: I896UXJL1
cognition 3.04

Any suggestions would be greatly appreciated.

If your phone has the extended power menu (hold power for options) there is a data network mode option, make sure it is activated. You may have hit it by accident.

I can try that, but do you know if its going to stay on 3g?
When I reboot I get 3g temporally but it goes away.

and yes data is activated

edit: So i kept trying to do what you guys said, but still nothing. FYI, edge is really slow

What modem are you using? Have you tried flashing a different one?

Have you tried other roms?

I would consider going back to stock (sucks I know) for a few days and if it continues to happen, take it into att and see about a new sim card or a replacement. If it doesn't happen again, try a different rom.

Try going into settings - wireless and network - mobile networks - Access point names - Click the menu button - Reset Defaults.

Had a co-worker running stock and his 3G would not come on anymore I had him do this and has been working ok ever since.
