I just did a sync on my ipod touch 4g and had a bit of a clear out to make a little room. I noticed that it's saying there are around 15 books on there. I can't find them anywhere on my ipod, nothing comes up when I search the device for the titles, and there's nothing stored under BOOKS. Oh, and I have no book apps. I deleted all the titles from my imac, but when I did my sync, it's copied them all back over from my ipod. This is driving me crazy!! How do I find & delete these books when the ipod is saying they're not even there!!?? Thanks.
