Why don't you try to get a page content width:

var screenWidth = 0;
$(window).bind('resize', function () {
    screenWidth = $('[data-role="page"]').first().width());
}).trigger('resize');​​​

This will give you page content width, even if page is resized.

You won't always get perfect results while getting viewport screen dimensions ($(window).width()), different devices behave differently.

$(window).width() and $(window).height() will give you the viewport dimensions, not the screen dimensions. Here you will find detailed overview of this problem.
