How do I get the ringtone onto my phone?

What type of ringtone and from what source? You can sync your blackberry with both itunes and Windows Media player and save the music to your sd card. Once you do that, go to the song and highlight it and hit the menu button and you will have the option to set it as a ringtone. you can also various third party applications to make ringtones from songs so that you can customize and use the specific part of the song you like. I use RingtoneRemix, but there are many other apps that will do the samething.
