After No-Do, Mango will be update number 2 for Windows Phone, if you don't count that update to enable updates which didn't really work on first try and had to be updated again. Anyway, I wonder how many unpatched security holes IE mobile has by now. Good for them they don't get all the media presence Android and iOS do. Edit: Why the downvote? I remember iOS updates fixing plenty of security bugs so I assume there are lots of unpatched holes in WP7.
