A couple of things I dusted off over the weekend.
A WP7 Html TextBlock
This HtmlTextBlock offers a similar level of functionality as to that of its silverlight counterpart which is pretty close to the android equivalent. Its still a bit buggy at times when dealing with more complex tags like the html dtd tag but does the job.... WP7 Html Text Block. The design is largely based on this guy's, and rewriting the web browser related classes using html agility. One day I'll post the details but, blah... Not right now. lol
