The BookBook for iPhone 4, like its bigger brother, flips open like a book, revealing interior pockets for cash, credit cards, ID and other wallet-sized items. Now you can ditch your wallet and replace it with this case and carry one less thing in your pocket. The case also has holes in the right places for easy access to your handset’s hardware buttons, ports and cameras. From the outside, the handmade leather case with its hard-back covers and vintage finish. The new BookBook for iPhone 4 is available now at Apple Store and twelvesouth.com for $59.99.
