Remember the BookBook, Twelve South’s eautiful vintage book-style case for the MacBook Air we told you about two months ago? Well, it has come to iPhone 4, not unexpectedly. By the looks of it, book lovers, retro fans and just about anyone in a market for a stylish, premium case for their glass-and-metal Apple handset should be taken care of. 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.

Talk about convenience – 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 lends itself perfectly to the fans of Indiana Jones memorabilia. Interested? Head over to the Twelve South online store where BookBook for iPhone 4 retails for sixty bucks.
