I have had my HTC Desire on orange (who incidentally are terrible) for a few months now and have noticed in this period of time that my 3g connection has been gradually getting more and more intermittent. It has now gotten to the point where it just doesn't connect at all to 3g or show the 3g logo at the top of the screen next to the signal strength bar.
So, I have now factory reset the phone, and still no joy. Does anyone have any suggestions as to how I can get this working?
The phone has not been 'unlocked' from orange.
