CIA World Factbook apps for the iPhone
I have been looking for this like this:
The CIA World Factbook is arguably the best value for a research almanac, bar none. The Factbook provides detailed information on the geographies, economies, populations, and militaries of more than 250 nations and territories spanning the globe. And all of the information is in the public domain, making it an attractive resource for developers to repackage and sell for the iPhone and iPod touch.
