I recently purchased an iphone 5s. I had an iphone 4 in which everything was backed up to iCloud. When I activated my new iphone, all my ringtones were there. The problem came when I upgraded to the latest version of iTunes, suddenly all of my ringtones simply disappeared from iTunes and from my iPhone as well. I had not purchased these ringtones, they were ones I made myself using Garage Band. So, I had to do them all again. Here is a good link to tell you how to make ringtones using Garage Band.
