Here's my situation; I've built a very simple web app that looks up a users location and plots it on a Google map. Here's my code: http://pastebin.com/d3a185efd

When I test it, my location is detected as being >= 500 meters from where I actually stand.

BUT

When I open up Google Maps or Gowalla my location is correct to within <20 meters?

So my question is: Do native iPhone apps benefit from a higher accuracy rate than web apps?

If so, why?
