Amazon on Thursday updated its official Kindle app for iOS less than 24 hours before Apple’s new iPad launches. The Kindle 3.0 update adds a number of improvements, including a new eBook library design, cloud view and support for the new iPad’s Retina Display. The new library design facilitates easy access to a user’s books no matter where they are stored, with a new grid view and two tabs labeled “Device” and “Cloud” much like the layout on Amazon’s Kindle Fire. The update is available now for free in the App Store.
