This is odd. When I download pics they go to "cam roll" and look fine. But after when I move them to another folder (say a created one) the same pic look "grainy" like little white noise that become even more obvious as I zoom in. Also I have 2gigs of pics yet my iPhone use 4 gigs. I checked and it's 4 gigs of photo data cache.... Then fine. When I sync my photos it says "optimizing" photos. I guess that would explain the double size, BUT then again why the FCK are my pics all grainy compare to the originals?
