I'm having trouble making phone calls (and receiving them - the caller gets told the number is invalid) sometimes. When I dial a number it starts off like its going to ring, but before it does it just puts up a 'disconnected' message and then stops.
I'm with T-Mobile, and thought this might be a cell problem, but I was able to call them from a different T-Mobile phone when mine wouldn't make a call and they say its a handset issue. However, the phone is now working fine (I'm in a different city).
Anyone come across this before, and if so how did you solve it? I don't have a nearby repair centre otherwise I'd get the firmware upgraded (I'm on 3.12) just to see if that would help...
Thanks!
