For some reason my 7600 keeps losing its signal, if I switch the phone on I have say 3 bars lit then after the screensaver shows the clock if I then press any key to bring the phone back to life then the signal has gone. If I then switch the phone off and
back on again the signal returns???????? Anyone any ideas whats happening?

Just out of interest the phone is on PAYG connected to the o2 network
