Usability 
CoolSmartphone is another Microsoft Smartphone focused site. The mobile version has a collection of mobile friendly links as its front page. Look carefully and you will see two links to the site's own mobile content. The first, labeled Latest CoolSmartphone News is basically a blog containing new product announcements and Windows Mobile tips and tricks. Then there is "My Blog" which is the mostly off-topic and rather entertaining blog of Gears, the site's webmaster. Gears is currently on honeymoon so things are a little slow at CoolSmartphone right now.
A word of warning to those of you on lesser phones, both the News and Gears blogs are rather heavy (40-50 KB worth) on graphics for a mobile site. The Openwave browser on my Moto i855 threw up it's hands at both pages and refused to download most of the images. Opera Mini had no problem loading the pages in seconds, including all the images, over a slow 40 kbs connection. I can't say it often enough, if your phone can run Opera Mini, get it. Opera Mini will completely change the way you look at the mobile web.
