Perform a custom reset... (*2767*2878#)
If you still have the same problem then perform a full reset... (*2767*3855#)

NOTE: Latest SUS is 051218.

I have done the same and had the same problem

If you go to band selection (under network settings) change it to 900/1800 (it will be set to "Tri Band") then your problem is solved.
