Amazon has updated the Kindle app for iPhone and iPad, adding some basic improvements to the standard assortment of reader functions. These include the addition of “print replica” textbooks so students can follow along with the paper copy in class as well as improved PDF support and a personal document system that lets you send files to an Amazon address for conversion.

They’ve also improved the magazine interface for easy downloads and storage. You can also sideload PDFs for reading on the go.
