the phones front speaker has a sensor in it? what is it capable of? i noticed it when i was on the phone, and the screen went dark when somthing covered it. (sheer Genius lol) is it possible to make it detect a hand being waved infront of it? it'd be cool to wave your hand to turn pages, somthing to "show off". But it may just be a "1 or 0" type thing. anyone know?
