Does anyone know whether the iPhone supports or will soon support the W3C Geolocation

Does anyone know whether the iPhone supports or will soon support the W3C Geolocation specification?

I’m looking to build an app for mobile users, but rather than spend the time developing apps for every different platform (iPhone, Android, etc…), I’d much prefer to create a web app that makes use of the W3C Standard.

    This code worked for me — on the iPhone web browser Safari and as an added bonus it even worked with FireFox 3.5 on my laptop! The Geolocation API Specification is part of the W3 Consortium’s standards But be warned: it hasn’t been finalized as yet.
