title: phonegap geolocation always fail on timeout
body: <p>I'm using sencha-touch 2.0 and phonegap 2.0.0 in my app to retrieve user's location.
  When runing on my locahost, everything works just fine. However, when loading the .apk to my android 15 api's device (using eclipse and the adt plugin), every call to getCurrentLocation or watchPosition never returns...</p>
  
  <p>here is my code:</p>
  
  <pre><code>geoOn: function(){
      var geoReady = navigator.geolocation || undefined;
  
      var onSuccess = function(position){
              Top5.app.alert('Geolocation success '+String(position.coords.latitude) + ' ' + String(position.coords.longitude),'Geolocation');
              var scope = Ext.getCmp('nestedList');
              scope.updateDistance(position.coords);
      };
  
      var onFailure = function(error){Top5.app.alert('Geolocation failed: '+String(error.code) + ' '+String(error.message),'Geolocation');};
      if (geoReady) {
          this.watchId = navigator.geolocation.watchPosition(onSuccess ,onFailure,{timeout:6000,maximumAge: 3000,enableHighAccuracy: true});    
      }
      else{
          Ext.device.Geolocation.watchPosition({
                   frequency: 3000, // Update every 3 seconds
                   callback: function(position) {
                          this.updateDistance(position.coords);
                   },
                   failure: function() {
                     console.log('Geolocation Failure!');
                   },
                   scope:this
          });
      }
   },
   geoGet: function(){
       var geoReady = navigator.geolocation || undefined;
       if (geoReady) {
  
           var onSuccess = function(position){
               Top5.app.alert('Geolocation successful!!!');
               var scope = Ext.getCmp('nestedList');
               scope.updateDistance(position.coords);          
           };
           var onFailure = function(error){Top5.app.alert('Geolocation failed: '+String(error.code) + ' '+String(error.message),'Geolocation');};
           navigator.geolocation.getCurrentPosition(onSuccess,onFailure);
       }
       else{}
   },
   geoOff:function(){
  
       var geoReady = navigator.geolocation || undefined;
       if (geoReady) {
           navigator.geolocation.clearWatch(this.watchId);
           this.watchId = null;
       }
       else{
           Ext.device.Geolocation.clearWatch();
       }
  
   },
   updateDistance:function(coords){
       Top5.app.alert('updateDist','');
       var scope = Ext.getCmp('nestedList');
       var lat = coords.latitude,lon = coords.longitude;
       var store = scope.getStore();
       var i,record;
       for(i = 0; i &lt; store.data.all.length; i++)
       {
           record = store.data.all[i];
           if(record.data.locationX){
              record.set('distance',Top5.app.getDistance(record.data.locationX,record.data.locationY,lat,lon).toFixed(3));
           }   
       }
  }
  </code></pre>
  
  <p><strong>UPDATE:</strong> So I walked out of my building and it worked... I need to go outside more often.<br>
  However, when I'm disabling the gps, I thought geoLocation will find my location using wifi connection - but it failes (I'm setting enableHighAccuracy: false). Why is that?</p>
  
  <p><strong>UPDATE:</strong>   Let me rephrase my question:
  Does navigator.geolocation.watchPosition suppose to work both with GPS signal and wifi/g3 signals? How can I detect user location using internet connection only? currently, my code is working only with GPS, and when that option disabled or signal is blocked, geolocation isn't working.</p>
