Barnes & Noble has just released an updated version of its free Nook for iOS app. It has been optimized for the new iPad and its Retina display with sharper graphics, words, and images. Otherwise, 3.1.3 brings with it more reading options, letting users have single- or dual-column views when in landscape orientation on the tablet, like in an actual book. The highlight feature is also now much easier.
A number of bug fixes have been applied in this latest software. The update requires iOS 4.3 or newer and is compatible with the iPod touch, all iPads, and the iPhone 3GS, 4, and 4S.
