create "shiny" effect using css gradient

Question

Is it possible to create a gradient like that of the shiny effect on the iphone in the link below using only css?

I've tried using the following code but it isn't "shiny"

background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(255, 255, 255, .15)), to(rgba(0, 0, 0, .25))), -webkit-gradient(linear, left top, right bottom, color-stop(0, rgba(255, 255, 255, 0)), color-stop(0.5, rgba(255, 255, 255, .1)), color-stop(0.501, rgba(255, 255, 255, 0)), color-stop(1, rgba(255, 255, 255, 0)));
background-image: -moz-linear-gradient(top, rgba(255, 255, 255, .15), rgba(0, 0, 0, .25)), -moz-linear-gradient(left top, rgba(255, 255, 255, 0), rgba(255, 255, 255, .1) 50%, rgba(255, 255, 255, 0) 50%, rgba(255, 255, 255, 0));
background-image: linear-gradient(top, rgba(255, 255, 255, .15), rgba(0, 0, 0, .25)), linear-gradient(left top, rgba(255, 255, 255, 0), rgba(255, 255, 255, .1) 50%, rgba(255, 255, 255, 0) 50%, rgba(255, 255, 255, 0));

I've created a container in this jsfiddle -> http://jsfiddle.net/3qWYL/
