I can make the calls (I did ring but I did not speak), or rather: when I try to close the call, I block the call application on the red button that does not go away ( stuck)
Yes, I have exactly the same.
I have just today noticed that the 3G is not working. It does not detect any networks so I cannot register on my network with my working sim.
Wifi does work but the 3G SIM version does not...so I'm not sure why there is a 3G version if it does no...
