I have OZ 3.5.3 flashed on my C1000. I'm very happy with it overall (much better than Sharp's ROM). I just have one nagging issue (which I suspect I caused):
Somehow I've managed to end up with the screen rotation 90° off from the screen rotation. For example: When I hit 'right' apps in Opie act like I hit 'up.' When I hit 'up' they act like I hit 'left.' Everything works correctly in a terminal (not a terminal window, but VT 1). So if someone can tell me how Opie keeps track of screen rotation in relation to keyboard orientation I would be eternally greatful. I don't need a step-by-step explanation. I'm perfectly happy to RTFM...I just couldn't find the FM in this case.
