Thank you for sharing this with us. For those of us that use swaptunes to sync with two seperate computers this is very helpful. Before this I had to copy the ringtones off the phone through ssh an then resync them on each of the two computers (ringtones added through iTunes store them in the /var/root/media/iTunes_control.... folder and swaptunes renames that folder depending upon which computer your syncing with). So if I had it set for my home computer it would play one ringtone and then if I swapped it to the other computer a default built in ringtone played instead.
Using this method all my ringtones are seen by the phone as built in ringtones and always available. Very nice find and thank you again for sharing the information with us.
