Thats great, but…as we all know from using an iPhone experience, the user’s location accuracy is not great from the initial request to get a location. When using google maps it takes about 30 seconds to turn on GPS and find a location with hight level of accuracy.

Thats why I think it would be much more useful to use navigator.geolocation.watchPosition.

What would be great to see is some code example where it tries to find a best possible accuracy within say 30 seconds.

Omarius,

There are several JavaScript-based IP geolocators. That’s the route I’d take, because it will work for almost all of your visitors. The easiest comes in Google’s Ajax Loader, which would be convenient because you can use it to load Google Maps, too (assuming you use it).

More about it here:
