Custom Ringtones?

[fddrummer06]

Ok, I've been searching for about an hour now and can't find any answers so I'm making a new topic. I've made some custom ringtones and tried putting them onto my phone, but I can't get them to show up in the list to select them. I've tried both wav and mp3 and can't seem to get it to work. I've done the registry hack to point WM to a folder on my storage card and that didn't work either. What am I doing wrong?
