I just bought a ringtone on my iPhone 4 by going into Setting > Sounds > Ringtone and there clicking on "Buy More Tones" on top.
To my astonishment it didn't show up under the list of "tones" in Settings > Sounds. I do see it in my music library within the iPod App though.
I thought maybe syncing will fix things, but not so. After syncing I can find it in the iTunes library under Library > Music but not under Library > Ringtones.
It also shows up under Store > "Purchased on XXX".
When the phone is connected to the computer the ringtone doesn't show up under the "Ringtones" tab either (having selected the phone on the left).
How do I get it from the music library to the ringtones?
