10 Simple steps just follow them “EXACTLY”
1. create ringtone
2. import file into itunes library
3. right click on file and create AAC version
4. drag AAC version to desktop
5. delete AAC version from library
6. rename AAC version on desktop (which will say m4a) to end in file name m4r
7. it asked me if I was sure I wanted to do that, so click yes to m4r
8. import m4r back into library (and for me, it also imported it into Tones folder then)
9. sync with iphone, ipad etc making sure the ringtone is either checked or ALL tones are checked
10. good to go
