Twelve South has unveiled a “classic black” version of its BookBook for iPhone 4/4S as well as a refreshed vintage brown version. Like the original, the new black version of BookBook marries a wallet with an iPhone case.

The Classic Black BookBook for iPhone, designed at the request of customers, and the Vintage Brown BookBook for iPhone are available now at http:/ and soon at Apple stores for US$59.99.

The hybrid wallet and iPhone case looks like a pocket-sized book. It holds a driver’s license/ID, credit cards, cash and iPhone, eliminating the need for both a traditional wallet and an iPhone case.
