I'm having issues with audiobooks on my iPhone ever since I updated to iOS 4. I have a bunch of audiobooks that used to he sorted correctly by book when viewing on the iPhone. When I first synced my iPhone after updating, the audiobooks still showed ok, sorted by book. But after the 1st sync, the sorting of the audiobooks changed. Now, all of the individual chapters (all the individual files) are showing together without being sorted by their corresponding book. In iTunes, they are sorted/grouped together correctly, but on iOS 4, they audiobooks section is just one huge list of chapters, sorted by name alphabetically. Anyone know how to fix this?
