Hi, and welcome aboard :)
Take a look at
http://www.remi-grumeau.com/labs/iui/geolocalisation.php
It uses the HTML5 built-in geolocalisation method, supported on iPhone
Safari and desktop Firefox (since 3.5.x afair)
function getPosition(position)
{
// PROMPT THE LONGITUDE
alert(position.coords.latitude, position.coords.longitude));
alert(position.coords.latitude, position.coords.latitude);
}
function errorCallback()
{ alert('error'); }
function myPosition()
{
// GET GEOLOCALISATION INFOS FROM THE BROWSER
navigator.geolocation.getCurrentPosition(getPosition, errorCallback,
{maximumAge:600000});
}
