Can you save MMS videos on iphone 3g

[copper]

Please help. I know you can save a picture to your camera roll by holding down on the picture then saving it, but when you try on a mms video all you get is a still. I am I just dumb or is there a way to do this. Any help would be great.

bottom left corner is the save video button, this may only work with compatible itunes video files, things like animated gifs and wav files have no wheres to save...
