Hi -- So I downloaded iOS8 and updated my iPhone 4S. For whatever reason I got an error and it required a restore. Thankfully I had made a backup right before. When I restored and opened iBooks for the first time, I had all of the documents I would have expected. But within a second or two they disappeared! Poof. The must be in there somewhere, right, since they showed up for a few seconds - there's no ghost in the machine. It's incredibly infuriating. I had hugely valuable highlights of maybe a dozen books in there. I thought that's what the purpose of a backup was. Several sort-of-similar threads in other forums have suggested syncing from iTunes on the computer. However, this did not work for me since I managed my books manually on my iPhone and thus do not have copies of the books (let alone the highlights!) on my computer. These books, I should note, were not bought through the iTunes store (they were legally free!). Any help would be hugely, immensely appreciated! Thanks.
