I talked about the Skyfire browser back in January and tried it on a couple of devices over the last few months. I read on Brighthand that the private beta has been expanded to a public beta so that anyone can download and try it out. The Windows Mobile client is now also up to version 0.8. Simply visit the Skyfire site and sign up.
I just installed the latest version on the Touch Diamond and HTC Advantage and realized I only currently have VGA Windows Mobile devices in house. I can't get Skyfire to work on the Touch Diamond and while it does work on the HTC Advantage in portrait mode the fonts are not clear and crisp and Opera Mobile is a much better experience on both of these devices. Be aware that you can only run Skyfire on one device with a single account too. I will try it out again on my Treo Pro when it arrives because I have heard good things about this browser.
You can also download Skyfire version 0.6 (0.8 is coming soon) for S60 devices. I need to put it on my Nokia E71 soon and give it a try as well.
In other Windows Mobile browser news, Microsoft announced Internet Explorer Mobile 6 back when they announced Windows Mobile 6.1 in April. However, IE Mobile 6 (aka 6 on 6) news has been lacking since that announcement and we are still waiting for the free update. Arne Hess has gotten a hold of some screenshots of IE6 Mobile and while it should improve the current implementation it looks like Opera Mobile 9.5 may still be the best browser on Windows Mobile.
