Have a user who dropped their T-Mobile 8320 Curve and now the T-Mobile wireless network is not working. It will search for the network and eventually say no network found. The wifi part still works though. I ran the Diagnostic test and it says no for the radio data activation. Also when the mobile network is turned off it shows a red X where the signal bars are instead of saying off.

Anyone have a clue what happened?

Maybe the cell radio antennae was damaged during the drop?

Took the phone apart and couldn't really see any damage to anything, but I could have overlooked it.
