Samsung SCH-U740 Alias

I was at the Verizon store the other day, and I asked one of the associates about using my own .mp3s as ringtones. Since Verizion has a strict policy about copyright laws, he mentioned that I go to phonescoop to get my answers. He also mentioned that there was a program that will allow me to use the USB cable that came with the music essentials kit, and that could cut the song I wanted in anyway as a ring tone, but he couldn't tell me what it was either. I currently use Audacity to cut the song the way I wanted and used a friends LG VX9400 to send the file to myself. Does anyone know that program he spoke of? Please let me know.
