How do you send a ringtone/song via bluetooth to another phone, using the Blackjack 2?

I can recieve songs, but cannot send songs via bluetooth. I've tried going to the folder, then (selecting) the song, then going to menu, send via, and the bluetooth is NOT highlighted so I cannot click on it to send. The only ones available for me to use are "send via email" and "send via text message." Please help! I've checked the guides, FAQ, and trouble shoothing, but can't find anything that will help...
