The 83xx series has always had a low end camera, also you are viewing them on a low resolution screen. Between the two, the quality never looks amazing unfortunately.
It's not a boost issue nwl. RIM made the blackberry. All the 8330's have a 2mp camera. I have taken pics off the bb, doctored them up a bit with a good PSP program and then put them back onto the media card. If your using them for a background for your home screen it really helps.
