I have NGAGE QD which has blue tooth. once i tried to copy mp3s to my phone by blue tooth but i wasnt able to do it. i think i wasnt able to do it because i tried to do it with the nokia pc suite. but i could not transfer it directly without the pc suite cos my phone memory was less, and even if u do manage to get the mp3 to ur phone by bluetooth, u will still have to move the file to ur memory card, if u didnt copy it on ur memory card that is. and the file manager is really bad in 3230, i recommend u to install a file manager also in ur phone
