Re: iPhone app – can't add second camera?

When I upgraded to iOS 4, I had pictures in 3 places. These seemed to correspond to places I had used my iPhone 3GS camera (Placed didn't show a map, just the checkerboard pattern). When I went to take a picture with the iPhone camera, I was prompted for permission to use my location—I gave it. Now I have only a pair of pictures taken at my home, the other locations are gone. I don't have the latest version of iPhoto. Has anyone else seen this?
