The Skyfire mobile browser is now available in public beta. If you haven’t tried it yet, you should; the browser is pretty neat, is fast, and works great. Currently, the Skyfire browser is only supported in the US on Windows Mobile (5 or 6) and Symbian platforms (Nokia N or E series 3rd edition).
See the Skyfire Open Beta registration page.
