Amazon released a minor update to its Kindle app for iOS this week. Kindle 2.1 features a few tweaks that are aimed at iPad users, and one major new feature for iPhone/iPod touch users.

The iPad version gets bigger fonts and more font sizes as well as faster navigation between home and archived items.

The iPhone and iPod touch version now allows you to search for any term inside a book. If you ask me, the ability to search is one of the things that really gives eBooks a leg up on physical books, so it’s nice to see this feature making its way to the iPhone version of the Kindle App.

Amazon is also promising a few nifty features to look forward to in the next release, including search-in-book functionality on the iPad, Google and Wikipedia word lookup, and instant word-lookup in a dictionary with 250,000 entries.

The Amazon Kindle app for iOS is available as a free download from the App Store.
