I recently added the iBook Search Pro app to my new, 32gb iPad Air. For practice, I downloaded a small children's book, Alice's Adventures in Wonderland. However, when I tried to open that book later while in the car, it wasn't there. A message popped up saying that I wasn't connected to wifi. Well, duh. I understand that this is not an iPhone. But I assumed that I had downloaded the book to my iPad (as I hope to do with many books in the future) so that I could read it wherever the heck I was. What is the problem here? How do I use this iPad as an ereader when not on wifi?
