After I upgraded to iOS 5 on my iPad 2, iBooks no longer shows any cover art for ePubs that I have imported. Anything that is from the iBook store shows art fine, along with PDFs.
Is there a solution to this?
Yes, I found that if you remove the books from the iPhone, then add them again via sync the cover art should return.
Try removing all iBooks form the iPad and the re-sync them again that fixes it.
