Since I upgraded to iOS 4, pretty much everything has worked fine, except my photos are missing on the phone. Well, they don't seem to be missing, since iTunes indicates that they are taking up more 350 MB of space. Also, when in the camera app, the lower right box still shows the last photo I took with the camera before the upgrade. So it seems that the photos are on the phone, but when I go to the Photos app, it tells me there aren't any photos in my library. Has anyone else seen this happen? Or have any suggestions?
