I use the Amazon Kindle app on my iPad all the time, and it has just been updated to version 3.5.
The Kindle app is optimized for the iPad, iPhone, and iPod touch, giving users the ability to read Kindle books, newspapers, magazines and PDFs on a beautiful, easy-to-use interface.
You’ll have access to over 900,000 books in the Kindle Store. Amazon Whispersync automatically syncs your last page read, bookmarks, notes, and highlights across devices (including Kindle), so you can pick up your book where you left off on another device.
