Motorola V710

i bought my v710 the first week that it came out. my buddy bought his on saturday(10/12/04). i noticed the software version is the same. however, the cameras operated at different speeds. when holding both cameras side by side, and taking the same picture at the same time, my camera took at least twice as long to process the picture. his was pretty much instantaneous. also his picture quality was better. mine was grainy. i wonder if they made a slight hardware upgrade, or tweaked the camera.
