How do I create custom ringtones for the Samsung Blackjack II?

well.. ive had the blackjack 2 sinse june. if you want to save a file on audacity you need so save it "filename.mp3" if you dont put ".mp3" it wont save as a music file. and then click open, click on your ringtone, and then drag it into your blackjack2. In order to do this though you need to go to settings, connections, USB, and make it m storage. oh. and you must have a sotrage card or you cant do this. then go to my stuff, sorage card, and click on the folder you put your ringtone in. confusing huh? :]
