TwelveSouth, the same company that brought you the BookBook MacBook casings has decided to shrink the design down with the iPhone 4 in mind. So instead of looking like you're carrying around a huge tome, you now look like you're carrying around a smaller tome which judging by its looks could totally pass off as a Bible; in fact, load your iPhone 4 with a Bible app and it wouldn't be too far from the truth. It looks pretty good and very classy from afar, although some reports are indicating that the "spine" of the casing is made out of distressed embossed leather which sort of cheapens the whole effect.
