The upside-down cellphone design

Would'ja believe that you could get used to doing all that thumb-texting if your cellphone's keypad was placed above the main display? We're not sure how a patent could be filed on a handset design that places the keypad at the top and the display at the bottom, but it's been done apparently. Umm, would having part of your palm obscure the display while you would be slamming out those T9 words to your buddies or significant other? We're not sure -- but perhaps we'll see the upside down phone design soon. Or not.
