For those with a quest for more information, useful or otherwise, Wikipanion is another free app the gives you access to Wikipedia. It’s like having an encyclopedia in your pocket – but less painful.
Like most free applications there is a bigger brother version, the Wikipanion Plus. A little more expensive that most apps but this full version keeps track of entries that can be stored for easy browsing. There is an update for 3.0 with extra features that is pending Apple approval. Check out Robert Chin for more information on this great iPhone application.
