If you've got the iPhone or iPod touch version of Amazon's Kindle App [Free - iTunes link] check your updates because the new Kindle 2.0, universal binary version with iPad support is now live in the App Store!

Boasting 450,000 books (for US customers, international availability varies), and Whispersync convenience between Kindle device, iPhone, iPod touch, and now iPad, Apple doesn't seem to have a problem with duplicating iBooks functionality.

It also says you can shop the Kindle store, though whether that means you can do it within the app, like iBookstore, or if you still have to go to the Amazon.com website first... we'll find out tomorrow.

If you're a Kindle Books lover, let us know how you enjoy reading them on your iPad!
