If you’ve been keeping an eye on Pinstack and the beta version of the next Viigo RSS reader, you’ll be happy to hear that it’s ready to rock. For those new to the party, Viigo is BlackBerry app which lets you view categorized feeds for a whole range of different subjects. Additionally, you can add in RSS feeds from any web site which has one. New features in version 2.2.7 include a registration wizard, an optional guided tour to help users find their way around the massive library of channels, visual notifications for unread channels, alerts of feed updates integrated with existing BlackBerry profiles, channel renaming, and an improved channel updating system. One of the cooler upgrades is now you can access your feeds from any BlackBerry or Windows Mobile device, as well as manage feeds on the web using your Viigo log-in info. Awesome upgrade, on the whole. So, uh, why are you still reading this? Go download. Chop-chop.
