Just download "Auto Rotate Switch" and leave on the Landscape Mode setting. You can map the Auto Rotate Switch to a button on your Bionic, I have it as my long press search. Meaning I hold down the little magnifying glass and it will turn the phones auto rotate on or off. I usually leave it off, unless I need it, then I just long press the search button and turn the phone like you normally would to go to landscape. When I'm done, I long press it again, and back to normal. Extremely useful.
