Jay Montano's My Nokia Blog is one of my favorite Nokia specific sites. Covering Symbian and Maemo and updated daily, the site is full of tips for making the most of your Nokia smartphone. There are also reviews of the newest Nokias with plenty of quality photos and videos and a catalog of free apps, games and themes.
Jay recently got his hands on an N900 and has done an extensive review and several videos of it and has posted a couple of Maemo tips articles.
As a WordPress.org site, My Nokia Blog benefits from WordPress' built in mobile support which detects mobile devices and delivers a couple of different mobile formated themes, one for touch devices and one for non-touch.
