few more things:
1. double tap the power button above the phone to turn off the screen
2. tap it again to turn it on

#2 doesn't work. i have to tap twice. when doing #2 in portrait mode, the background image gets corrupted (i see large chunks of square black space). once, there was no image loaded at all. the entire screen was black and i had to guess where the slider was to unlock the phone.

second thing,camera app screws up (viewfinder messes up) when auto rotated. perhaps an option to select which apps can be excluded from auto rotation might help?
