title: iOS 6 breaks GeoLocation in webapps (apple-mobile-web-app-capable)
body: <p>I have an app that does a simple textbook navigator.geoLocation.watchPosition(...) that works great in iOS 5.x both in Safari and as a web app (using apple-mobile-web-app-capable meta tag).</p>
  
  <p>However, in iOS6, GeoLocation does not work in the webapp.  It still works in safari as expected, but when I run the webapp, it prompts me for location permission, then silently fails.  I see the location icon, but no events are thrown from watchLocation.  I get no error events or any location events.</p>
  
  <p>Has anyone run into this?  Any workarounds?  It's definitely iOS6 specific and also specific to the apple-mobile-web-app-capable/webapp.</p>
