why can't they design a cell phone for students? as in, make it so that you can program your phone to go into "silent" or "vibrate" mode for a specified period of time. cuz seriously, i always forget to turn it to silent, or when i do remember, i then forget to turn it back to ring, and i miss calls. i know this is my own fault, but i think it'd be a nice feature to be able to program your phone like that.
