How do I get rid of the old ringtones on my sprint epic, and use the newly downloaded ones?

How do I get my sprint epic that is a refurbished phone from the sprint insurance, to not use the ringers from the old phone? I had the old phone for about 5 months and had downloaded a lot or fingers. But now that I have my new phone I only have 2. Those are he only two that I want to use, but it keeps using my old ringers and I have no clue how to access them because I can't find them on my phone.
