How to add ringtones to itunes after iphone4 is upgraded to ios6.0? Pay attention to the bell, not the music. How I wear it is always in the music.

Let me tell you the steps. Open itunes. Select a music with the right mouse button, and then click Show Introduction-Options. Fill in the revelation time and stop time (be careful not to exceed 40 seconds) -OK, right-click music-create ACC format; After creation, right-click the created file-open it in WINS Explorer, and change the file format to m4r；; Then copy the file to the desktop and add it to the database with itunes. Congratulations. Self-built ringtone succeeded;

Above; That's it. I have questions to ask. Thanks for the adoption.
