get gps location from mobile phone

Question

I would like to know What is the best way to get the gps locations off multiple phones on to a googlemaps on a website. I just downloaded googlemaps with latitude on my phone. Is it only possible to query your own location with the public location badge, or can you also get the locations off your "friends". Anyone got experience with this?

If it's - not yet - possible to get multiple phone locations, what would be the alternative? I have to say that it must be gps based and not based on cellid because that one is to inaccurate.

You can use Google Latitude for it: http://www.google.be/latitude/

To make your own thing with the Google API, you can lookup your position on your iPhone in Safari with a special API: http://blog.bemoko.com/2009/06/17/iphone-30-geolocation-javascript-api/
