How do you change a ringback tone?

I have an EnV2 with Verizon network. I would really like to change my ringback tone, but I'm not sure how. Thanks!How do you change a ringback tone?
there are 2 ways! You can either go through your phone on the Get it Now! And choose get new ringtones, go through VZW Tones Deluxe, once you get into that program there should be an option at the top that says MANAGE,



go there and you will have to choose to manage ringbacks or manage ringtones







You can also log onto www.vzw.com and click on the features tab at the top and choose ringbacks.
