Workin’ on the jQM test for 3D transforms.

3d-test.js

function transform3dTest() {
	var fakeBody,
		doc = document,
		de = doc.documentElement,
		bodEl = doc.body || (function() {
			fakeBody = true;
			return de.insertBefore( doc.createElement( "body" ), de.firstElementChild || de.firstChild );
		}()),
		el = doc.createElement( "div" ),
		transforms = {
			'webkitTransform':'-webkit-transform',
			'OTransform':'-o-transform',
			'msTransform':'-ms-transform',
			'MozTransform':'-moz-transform',
			'transform':'transform'
		},
	//	prop = "transform-3d",
		ret;

	bodEl.insertBefore( el, bodEl.firstChild );

	for ( var t in transforms ) {
		if( el.style[ t ] !== undefined ){
			el.style[ t ] = 'translate3d( 1px, 1px, 1px )';
			ret = window.getComputedStyle( el ).getPropertyValue( transforms[ t ] );
		}
	}

	bodEl.removeChild( el );
	if( fakeBody ) {
		de.removeChild( bodEl );
	}

	return !!ret; // || $.mobile.media( "(-" + vendors.join( "-" + prop + "),(-" ) + "-" + prop + "),(" + prop + ")" );
}
