Sometimes backing up the iPhone in iTunes during a sync takes a while. According to Apple, now there's a new way to speed up the process.
Backup times can suffer when there are a large number of photos or videos on the Camera Roll. To speed up your iPhone backup the media files must be imported to your computer, removed from the camera roll, and re-synced to the iPhone.
Users are reporting a bug in iPhone firmware 3.0 that prevents photos from appearing on the camera roll. Although image files are present on the device and can be copied with iPhoto, thumbnails are hidden on the camera roll.
The camera roll even counts the correct number of photos as it hides a portion of the files. Users have determined the problem arises when numbers in photo filenames exceed 10,000. For some reason the iPhone OS 3.0 camera roll does not display these files.
