After updating the iPhone to OS 3.0, my camera roll tiles are all black. Clicking on a random spot in the black screen shows the actual picture in full size on the screen, but navigating back to camera roll tile view just shows a bunch of black tiles (actually just looks like a solid black screen. Anyone having this problem? Anyone have a solution? EDIT - Further review shows that if I take a new photo (after the 3.0) upgrade, the new tile shows a thumbnail of the photo, but the the pre-update photos just have black thumbnails. I would be fine just deleting all the photos from the phone, but have already imported them into my mac and don't see a way to delete them after importing anymore.
