I upgraded from an iPhone 3G to an iPhone 4 recently. My problem is that on my 3G I have a book "The Adventures of Sherlock Holmes" but after I set up my iPhone 4 I can't find it anymore in the iBooks store. I find now many more variants of Sherlock Holmes books but not the same one. I would really like to send this book to my iPhone 4 to finish reading it. Is there a way to do it?
