Someone has written some freeware utilities for rotating the screen 90 (RotateSE), 180 (RotateSE180) or 270 degrees (RotateSE270) here:

I found they work fine on WM5 or 6 or 6.1.
The lower right of my screen got worn out from using Block mode so much, and the 180 flip lets me write on a still usable part of the screen.
