Not working on IPhone 5s

Mobile Joomla works great for every device expect for the IPhone 5S. I have a template assigned under the IPhone tab, but when I try to go to the site on an IPhone 5s, it displays the desktop theme and not mobile theme.  Can someone tell me if the IPhone 5S is supposed to be supported?

Could you visit www.mobilejoomla.com/uatest.php on your iPhone 5S and post results here?

Same problem here:
