basically the signal strength shows something like 3 ASU, but phone is "emergency calls only" and network state "disconnected".
Toggling Airplane mode sometimes fixes this, so does doing a manual network scan and choosing o2. then it'll show GPRS and a higher signal strength (e.g. from 3 to 7 ASU) and work fine.
Pretty serious, because obviously calls can't be made or received and not obvious it's happened if user doesn't see the "emergency calls only" on pulldown (the signal strength indicator in status bar still looks weakly connected!).
I can't see what's triggering this but it seems to happen sometimes overnight.
Could it be connecting to wrong network? i haven't tried making an emergency call for obvious reasons.
Kernel problem? hardware problem? ROM problem?
Any chance updating baseband fixes this with ICS?
