well you first have to pair your phone with the bluetooth, then you can use that bluetooth to get ringtones and songs from friends. If you use the bluetooth to transfer songs and ringtones there is no charge, but the only thing is finding a friend who has a bluetooth capable phone who has songs you want
well idk about your bluetooth thing..
but if you go on www.phonezoo.com
you can make an account and its free to recieve ringtones, pictures, and sounds.
you have to save the sound as a ringtone when it comes in.
and if you look on phhonezoo and there isnt a song you want, you can use your own music too.
hope i helped.. if i didnt, sorry.
