Thanks Mike
I don't see how they could have got reversed, I simply plugged the loom connector into the back of the unit, same as I did with the old WinCE device.
Pity about the update as some of the bugs would seem to be OS/firmware specific ones and would have been cured by upgrading to 5.1 I'd have been willing to give it a shot having rooted and flashed a few phones in my time.
