Running Leopard on an iMac, with iTunes 10, and syncing iPhone 4. I have noticed recently the space taken up by my photos on my iPhone 4 changing radically. I have iTunes set up to sync all photos from Aperture. I noticed the space taken up on the iPhone as being 5.7 GB, which seemed a lot bigger than before. I synced the phone again, and it went down to 1.2 GB. Played around some and was able to reproduce this problem. Seems whenever I click refresh to update my podcasts, then go back to my iPhone on the left, under devices, the space taken up by my photos goes back to 5.7 GB. I sync again, and it goes back down to 1.2. I can do this endlessly. Strange, no?
