On my 8800 I've just updated the OS to 4.5.0.124 (it was 4.2 something) and I now can't even enable Bluetooth ! The icon's on my screen but through the Options menu I get an empty screen, and through the Bluetooth Setup I just get the constant message "Enabling Bluetooth". I have to remove the battery to stop this message and get no further. It seems that the update has lost Bluetooth.
Any ideas, anyone, would be very gratefully tried.

Regards.
Henry
