Do you like to share the books that you are reading with friends? Amazon’s latest iOS app update has a tool that lets you do so.

The new “Book End Actions” feature lets you send a tweet or a Facebook status update when you finish a Kindle book. You can also use this feature to rate the book and write your own review. The app will also recommend other books that might interest you and you can even add these titles to a wish list.

Other features for the Version 3.6 update include multicolor highlights so that you can highlight in four different colors. In addition, a brightness control feature lets you save your brightness setting across device sleeps.
