I have searched whole of internet and the forums,couldnt find a solution to my problem..
I was on os 3.0.1 ,that one day my phone showed NO SERVICE instead of the usual operator banner...
What I have done so Far,
Reset network Settings
Restored phone to latest firmware...Didnt work
Now degraded back to OS 3.0
Still I get no service......S
Please Urgent Help is Reaquired, As this phone is only and primary phone.
