I have looked around for a fix but haven't found any yet. When I create trimmed ringtones via the htc trimmer and assign them to a contact, they will work fine until I reboot the phone. I tried some fixes like moving the ringtones to the SD card and that has allowed the phone to find them upon reboot but it will not put the tones back with the contacts. Is there a way to permanently stick the ringtone to the contact so they don't un-link after a reboot?
