Of all the cases I’ve seen and used, this one elicited the most comments from my friends. The leather feels good and looks genuinely like a book cover. So much so my friends thought I had a small bible with me. Inside is an iPhone case and a wallet compartment, sort of. You won’t be able to put very many things into this. I have at various times; some money, credit cards and transit cards. Convenient but not a true wallet. But very useful for those nights out when you want to carry little in case they get forgotten after a couple of drinks. Nice but somewhat expensive. The Twelve South BookBook for iPhone 4/4S is available from Amazon.
