Geo location in web applications

'Hello, world' example for getting locations in web application. Check out the following page from iPhone (or FireFox 3.5) http://linkstore.ru/igeo/ Can you see the map? It is a basic example uses the following code:

<script type="text/javascript">

function handler(location) {

var map = document.getElementById("map");
var lat = location.coords.latitude;
var lng = location.coords.longitude;
var acc = location.coords.accuracy;


var s ="<img src='http://maps.google.com/staticmap?center="+lat+","+lng+"&size=300x200&maptype=mobile&zoom=16&key=your_google_map_key' />"
+"<p>Latitude: " + lat + "</p>"
+"<p>Longitude: " + lng + "</p>"
+"<p>Accuracy: " + acc + "</p>";

map.innerHTML = s;
}

if (navigator.geolocation)
navigator.geolocation.getCurrentPosition(handler);

</script>
