Got a new iPhone and the iBooks from my old one aren't on my account anywhere?

I just recently upgraded to the iPhone 5. And me and my friend are on the same iTunes account, but somehow he has all my books on his new phone but I don't have them, when I'm the one who bought them lol! I just swapped carriers but I don't get how that would affect iTunes. I'm logged in and I've logged in online and on the app and still nothing. I've looked under the purchased books tab a million times and on his they showed up and he downloaded them but they wouldn't show up on my phone. What do I do?

Try syncing the book in itunes then to your phone. They should be showing up on your book shelf to be downloaded from there.
