Getting a new iPhone 5s 64gb in the mail tomorrow. My current 64gb 4S is chock-full. Would like to start over on fresh install with iOS 7 and just install what I redetermine I really need. BUT - I have a bunch of apps that I don't want to have to start over on, games etc. Is there a middle ground here somehow? Also, my iBooks app is well organized with lots of books - how do I retain that with a fresh install?
