Definitely looks very interesting.

This from their site:

What you need to participate
A U.S. mobile phone number.
A mobile phone subscriber data plan with a mobile phone service provider (an unlimited data plan is recommended).
A mobile phone running Windows Mobile 5 or 6, both touchscreen and non-touchscreen phones are supported.
Phones we support
Skyfire will initially run on Windows Mobile 5 or 6 mobile phones in the United States. If you do not know what mobile phone platform you have, visit the Microsoft Windows Mobile phone directory to find out if yours is a Windows Mobile 5 or 6 device.
The initial beta release will support only Windows Mobile phones with full keyboards (QWERTY). If your Windows Mobile phone doesn’t have a full keyboard, please continue to sign up for the beta and we’ll let you know when it’s supported.
Soon we will support the Symbian platform.
Other platforms and geographies are on the roadmap, too.
