If you already own a Kindle, now you need to download the Kindle app for your iPhone so you can keep reading on your iPhone. Amazon has announced the Kindle app for the iPhone and iPod touch, which gives users access and read Amazon’s ebooks. The app is a free download from the Apple App Store.
You can also use the iPhone or iPod touch Safari browser to buy new titles from Amazon as well as synchronize what you’ve already bought. Amazon’s new WhisperSync technology will keep your ebooks bookmarked across both devices.
