iBooks
when i go into the purchased part of iBooks and try to open a file, it doesn't show all the books in the file. For example, i try to open All Books. It says there is 540 books in there but when i open it up there are only 20 showing. i would like to re-download books that i have previously deleted but it wont show all my books. i have made sure that i have all the updates for the phone and have done all the restarting of the phone and such. does anybody have any tips?
