If you are a BlackBerry user, Viigo is a must have application. Viigo is an RSS reader for the BlackBerry. You can use it to get the latest updates to you favorite RSS enabled Web sites or blogs. It allows you to read articles in the application it itself or you can go directly to the original Web page. Its very similar to having the mobile version of Google Reader. Another this it has in common with Google Reader is that it’s free!
