Geolocation issue on mobile site

Question

We are trying to implement geolocation on this mobile app, we get the prompt for location but its not actually updating. Tried to firebug and I am not seeing any posts or responses.

Does anyone see anything immediately wrong?

http://bit.ly/cCMlWv

here is our js function

(function($){

$.extend($.support,{
    geolocation:function(){
        return $.geolocation.support();
    }
});

$.geolocation = {        
    find:function(success, error, options){
        if($.geolocation.support()){
            options = $.extend({highAccuracy: false, track: false}, options);
            ($.geolocation.object())[(options.track ? 'watchPosition' : 'getCurrentPosition')](function(location){
                success(location.coords);
            }, function(){
                error();
            }, {enableHighAccuracy: options.highAccuracy});     
        }else{
            error();                
        }
    },
    object:function(){
        return navigator.geolocation;
    },
    support:function(){
        return ($.geolocation.object()) ? true : false;
    }
}

})(jQuery);

then we have this function that runs to get the data

<script type="text/javascript">

    var googleMapApiKey = "***********************";

    $(function () {

        if ($.cookie("current_address") == null) {
            $.geolocation.find(function (location) {
                $.ajax({
                    type: "get",
                    dataType: "jsonp",
                    url: getGeolocationUrl(location.latitude, location.longitude),
                    complete: function () { },
                    success: function (data) {
                        if (data.Status.code == "200" && data.Placemark.length > 0) {
                            var city = data.Placemark[0].AddressDetails.Country.AdministrativeArea.Locality.LocalityName;
                            var state = data.Placemark[0].AddressDetails.Country.AdministrativeArea.AdministrativeAreaName;

                            if (data.Placemark[0].AddressDetails.Country.AdministrativeArea.Locality.PostalCode) {
                                var zipcode = data.Placemark[0].AddressDetails.Country.AdministrativeArea.Locality.PostalCode.PostalCodeNumber;
                                $.cookie("current_zipcode", zipcode, {
                                    expires: 10
                                });
                            }
                            var address = data.Placemark[0].address;

                            $.cookie("current_address", address, {
                                expires: 10
                            });
                            $.cookie("current_city", city, {
                                expires: 10
                            });
                            $.cookie("current_state", state, {
                                expires: 10
                            });

                            $("strong.place").html(address);
                        }
                    },
                    error: function () { }
                });

            }, function () {
                alert("Your device doesn't support geolocation");
            });
        } else {
            $("strong.place").html($.cookie("current_address"));
        }
    });


    function getGeolocationUrl(x, y) {
        var url = "http://maps.google.com/maps/geo?q=" + x + "," + y + "&output=json&oe=utf8&sensor=false&key=" + googleMapApiKey;
        return encodeURI(url);
    }
