But adding salt, you're effectively lowering the freezing temperature of the water. This allows the water to cool to -5 or -6 celcius without freezing. This is why it cools the beer faster and colder than just plain ice water.
Oh so it is just that then on the Mythbusters? I thought they were adding it to make something have a reaction to create a cooling effect (like those cold packs).

In that Case Six Strings, it ain't gonna work.
