[closed] geolocate and display in map (dinamycally)

Hi again. I need something like next example: http://blog.robotnet.de/2011/03/30/html5-geolocation-with-openstreetmap-and-openlayers-for-android-iphone-ipad-and-ipod/ This example displays a slippy map, and I need a interactive map. What I need, is geolocate the current position, more well, I've read and participated so much in forums, but I still don't understand well.

What I need? I don't need a editor like Potlatch or JOSM, right? I'd need Xapi and OpenLayers ( or Leaflet ), right? But I don't understand well how use Xapi

Best regards, Daniel
