A couple of years ago I picked up an app called College Football Radio & Live Scores to hear the games on my iPhone when I can't catch them on TV. I believe my life has improved at least 8.5% since. I can use it to listen to whatever games I want and I think I only dropped a buck on it. My favorite is to filter by the top 25 teams, track the scores, and flip around between whatever games are interesting. Figured I would share this most excellent way to enjoy college football.
