swipeleft/swiperight not working on Fennec, Opera Mobile, IE7.5?

swipeleft/swiperight not working on Fennec, Opera Mobile, IE7.5?

The swipeleft/swiperight events function properly on desktop browsers, android and iphone browsers. But they seem to fail on all my emulators and simulators: Fennec, Opera Mobile, Windows Phone 7, and so on don't do anything when I try to swipe.

  1.     // swipe
        $("#slider").live('swipeleft', function () {
  2.       alert('swipeleft');
          rollSlider('-');    
        });



I am a bit confused, as I could'nt find similar threads for this issue. Are these browsers supported for this events yet?
