How do I delete SNS history on Samsung Fascinate?

I can get all of my history to erase from my Samsung Fascinate except the SNS history. (The private email messages that I send/receive from Facebook, specifically.) It stubbornly sticks around in the history tab under my contacts. Does anyone know of a way I can get rid of it?|||In SNS, hit the menu key, you should see option to clear it.
