Your FN keys work? Mine don't work at all... I press (even hold) FN and a key and I get the key I pressed, no special character...
Also, if you change the key mapping you are going to have to press POWER to end a call...?
EDIT: A question... I have to use LCDDensity to change from 210 to 240, but it restarts Android, any way of changing this before it loads the gui? Programs from market don't show completely, most of them are set to fixed 240 density...
