Plug the USB end of your iPhone's charging cable into a USB port on your computer, then plug the other end of the cable into the charging port on your iPhone. This iPhone-shaped icon is in the top-left side of the iTunes window. Doing so will open the iPhone's page, as well as a list of the content on your iPhone in the left-hand side of the iTunes window. It's a tab below the "On My Device" heading on the left side of the iTunes window. The Tones page will open. Click and drag the .m4r version of the song into the iTunes window, then drop it there. You should see the ringtone appear on the page. It's a white button in the bottom-right side of the iTunes window. This should only take a few seconds. Once you see the progress bar at the top of the iTunes window disappear, you can disconnect your iPhone from your computer (if you wish) and proceed with setting the ringtone.
