Last year RIM updated their Technical Knowledgebase to support RSS Feeds for topics spanning their entire solutions base. Granted not all topics may be covered but there is enough to keep you going. This is a great resource for learning the ins and outs out your BlackBerry and you will hear it quoted quite often on BerryReview. I highly recommend browsing through it.
Topics include All Categories, BlackBerry Built-In, Connect, Enterprise Servers, Internet Service, BlackBerry Unite!, BlackBerry Device Models (many current ranges)….many more.
RIM has sadly limited the amount of Feed information that can be viewed via the Feed Reader. This in my opinion is a bit BlackBerry unfriendly of RIM. Also viewing the Full Article may differ from one Feed Reader to the next, as the Page references require iFrame support. It is however easy enough to Send an Email to yourself with the Link reference for full review or to open it in the BlackBerry browser.
