Although there has been a few paid versions of Wikipedia apps turn up in BlackBerry App World, the official Wikipedia app has now been released as a free download for all BlackBerry PlayBook owners. The app itself has plenty of features built in such as nearby search, ability to open artices in the browser, read search results in different languages and even adjust the font size to whatever it is you may find comfortable for reading. If you're a Wikipedia fan, go ahead and grab the download from BlackBerry App World. Also, the code is Open Sourced so you can fork it if that's your thing. You'll find the Open Sourced resources on Github readily available for download as well.
