Voicemail folder

I have two voicemail msgs on my iphone 4s
I can hear them whenever i want and play them ( meaning they are not stored on some remote Sprint server but they are stored somewhere in my iphone )

The question is where ?
I can SSH into the iphone and retrieve these audios ?

Plz help

I dont wana lose one voicemail... its very sentimental to me
Im afraid after a while it might be gone
