Anyone that owns a cellphone has probably been bombarded with all of the possible add-on features that are available, such as super duper voice mail packages, call-id, block call-id, downloadable games, custom ringtones, etc. What I have just discovered lately is another fun customization for your cell phone, custom music clips that play for your caller when they are waiting for you to answer. I have some fun ideas for anyone that has been considering ringback tones for their cell phone, but is still undecided.
