I don't think it does right now, but at some point, WP7 will have to support HTML 5. Keep in mind that the HTML 5 standard is currently a DRAFT and could be several years before finalized.

>Did I read this correctly, that HTML 5 will not run on WP7? I am working on a phone/pda/ipad web app and I am using a lot of HTML 5 and css3. This could be a problem for me?
