What if Apple's iOS6 ringtone setting doesn't work?

Some people find that the ringtone of IOS6 needs to be synchronized with iTunes to work properly. Look at the following steps ~ 1, download the latest version of iTunes 2, and add the ringtone file to iTunes (drag the ringtone directly to the music and application management position in the upper left corner of iTunes, and a ringtone management will be automatically added). 3. Sync ringtones and iTunes to your iPhone, and ringtones will work.
