Wikipanion, Wikipedia for iPhone

Wikipanion Review
Wikipanion (iTunes link) is the best application out for Wikipedia on the iPhone and iPod Touch. This app is simply genius and gives you a simplified version of Wikipedia without leaving out any of the site's extra features. To simply the site to fit the screen size of the iPhone, the normal links that you'd see to each section of an article are foregone on the main screen. Instead, there's a small icon located at the bottom of the app that's similar to the bookmark button in Safari on the iPhone. Using this button, users can access all the sections of an article.
