The TwelveSouth BookBook range of cases have proven themselves to be some of the most popular iOS and OS X accessories available on the market. Uniquely imagined and beautifully styled, the BookBook case is basically a rather gorgeous looking wallet and iPhone case combo that is manufactured to look like a vintage book on the outside. The quality of the product speaks for itself but with current versions only being compatible with the iPhone 4 and 4S, TwelveSouth have found themselves issuing a statement about the imminent availability of a BookBook case made specifically for the iPhone 5.
