How to unassign a ringtone from a select contact

[popkurn611]

A while back I assigned a ringtone to one of my contacts and now I want one ringtone for all my contacts, so I set my phone ringtone and that one contact still has the old ringtone. How do I unassign a ringtone to this contact? I don't want a specific ringtone associated to this one contact. My other contacts when you go to edit say "no ringtone specified" but I can't even select that option to assign to my one contact that has the separate ringtone.

What about setting it to the ring tone that you want for everyone else?
