Answer 1

Use the HTML5 Geolocation API, here's the official spec and examples.

EDIT

I've updated my answer to include current browser support.

W3C Geolocation API support

Firefox 3.5+
Safari 5.0+
Chrome 5.0+
Opera
iPhone 3.0+
Android 2.0+

Other phones not listed above use Gears or their own, platform-specific APIs.

• W3C geolocation API
• Gears
• BlackBerry geolocation API
• Nokia geolocation API
• Palm geolocation API
• OMTP BONDI geolocation API

Ahh, will we ever have just one single API? :)
