In Short

Kindle isn't just the brand name for Amazon's line of iPad-competitor tablets, it's also the name for Amazon's iBooks-competitor ebook reader app for iPhone and iPad. All forms of Kindle, hardware and software, are linked with your Amazon account and let you read all the books you've bought from the Amazon.com Kindle book store. Unfortunately, due to Apple's in-app-purchase restrictions Amazon can't link directly to their Kindle web store from their Kindle iOS app, but anything you buy on the Kindle web store automatically appear in the Kindle iOS app.
