Answer 1

//If you are doing it on javascript or a framework like backbone, you will encounter this a lot you could have something like this

$MobileRadio = $( '#mobileUrlRadio' );

while

$MobileRadio.checked = true;

will not work,

$MobileRadio[0].checked = true;

will.

your selector can be as the other guys above recommended too.
