Barnes & Noble has had a scattergun approach to their eBook reader for different operating systems. Some features were available for specific devices, others were left wanting. Well today comes news of some leveling of the playing field. The iPhone and iPad now get caught-up with the pack.

There are still device specific features, but there is also now some ability to tie different devices together.

For instance, the iPad version has in-app content ratings, while the iPhone version includes cover art and text that’s customized for the iPhone 4 Retina display. Both the iPhone and iPad versions also let users customize their themes.

The Nook apps will synchronize your settings across multiple devices, allowing you to start reading a book on an iPhone or iPod touch — or even an Android phone, and pick up where you left off on an iPad since all of your Nook apps will remember the last page read on any device.

If you are an eReader, best check out these new FREE NOOK apps from the App Store.
