Which Devices Support Javascript Geolocation via navigator.geolocation?

Question

The iPhone supports geolocation in mobile Safari via the following call:

navigator.geolocation.getCurrentPosition(
  function(pos){
    var lat = pos.coords.latitude;
    var long = pos.coords.longitude;
  },
  function(){
    /* Handler if location could not be found */
  }
);

I'd like to build a good list of devices that have one of the following:

1. support this feature out of the box, or
2. support this feature with an upgrade, or
3. support geolocation with equivalent fidelity of data with some other snippet of Javascript.

I'm only familiar with my own device, so this is my list so far:

Out of the box:

1. iPhone 3GS

Supported, but only with an update

1. iPhone 3G
2. iPhone 2G (?)
3. PC or Mac computer with Firefox 3.5

Supported with some other snippet

?

What is the level of support in Blackberry, Android phones, etc?

Answer 1

Although I think it's a great practice to standardize on the (draft, by the way) W3C Geolocation API, it's worth noting that there are a few other options in the browser, which can be particularly helpful if you need to target an older platform.

• Firefox 3.1 had support for Geode, which uses calls to navigator.geolocation with very similar syntax.
• Loki is a plug-in built by Skyhook which works on Internet Explorer 6, Internet Explorer 7, Firefox 2, Firefox 3, Safari and Opera. The syntax is substantially different, but still easy.
• Google Gears provides a geolocation API with a syntax fairly similar to the W3C API syntax. You can install Google Gears on Internet Explorer 6+, Firefox 1.5+, Safari, Opera Mobile and IE Mobile.
