I just d/l-ed an app called ringtone mp3, and I got the monday night football mp3 downloaded onto my phone. How do I make it a ringtone now? When I open up the sound settings, my song doesn't show up. Im sorry if this is a newb question, but I cant figure it out. Eventually I want to make some of my contacts have individual ringtones, but I have to jump over this hurdle first. THANKS!!
