My Blackberry Bold originally took pictures with no problem. Now, it acts like it's taking pictures, but the files it saves are unviewable. When I try to look at them on the bberry itself, it just shows a little red x in the left hand corner of the screen. When I move them to the PC, the files appear to be .jpg of the correct size, but seem to be corrupted. I tried upgrading to 4.6.0.304, and still get the same results. Any ideas?
