iPad 2 64GB wifi+3g (don't use the 3G yet) - iOS 4.3 Unpredictably the books downloaded into iBooks disappear... I open the app and watch it remove them one at a time in split second intervals in front of my eyes! While admittedly it's a cool effect to watch, it offers little utility since I'd like to keep them to read. I have had to re-sync through iTunes or to re-download them from the purchased books section in iBooks app in order to get them back. ANYONE know if Apple is working on a fix for this? I see that many iPad owners that are complaining about this problem on the web but no word from Apple on it. If anyone knows something other than just reloading the books or where the conflict exists that leads to such a "feature" please let me know. Thanks a million!
