Twelve South BookBook case available on case2case

Well, it sounds like Twelve South's BookBook iPhone 4 case has you and your ridiculous smartphone-conversion anxiety covered. The little leather-bound sleeve not only masks your iPhone in what looks like a miniature Bible binding, but also acts as host to your wallet's contents. If you're looking to fool folks into thinking you're really reading a tiny tome titled BookBook.

One look and you’ll be hooked. Beautifully designed and hand
distressed using high quality leather, BookBook is a conversation piece.
A totally unique iphone 4 case that disguises your phone and wallet, while
protecting both. It’s a wallet that looks like no other and a case that
keeps your iPhone from looking like everyone else’s.

Protect your iPhone 4 between two hard-back covers. Fold the covers
back-to-back to talk. It feels great in your hand. BookBook allows
edge-to-edge iPhone access. No frames in the way of your thumbs here.
You can access all iPhone controls and ports with BookBook. Charge, sync
and use the headphone jack while your iPhone is safe and sound in its
phone book.
