no there wasnt a problem with 3G before flashing my phone..i could even see the 3G icon all the time but i did used the internet on my phone too much then..after i flashed it ,it started restarting sometimes and when on 3G and i connect on the internet i lose all the signal bars after some time,especially when using ebuddy,nimbuz or opera mini..but on some others applications that require internet connection it usually takes little longer before it disconnects..think i should call my network operator and check with them but im busy this days with my exam sesion..this happens for a lot of time..i can wait little longer untill i call them and see what they say..
