Wallets and phones go hand in hand. You rarely leave home without the two of them. Now you can carry both in one BookBook made exclusively for iPhone 4 and iPhone 4S. This little book has a convenient ID window and slots for your debit/credit cards, reward cards and cash. Instead of grabbing your wallet, phone and keys when you walk out the door, simply grab BookBook and your keys.
LOVE IT: I own this. It is hands down, the best case I have ever bought for my phone. It survived two drops & it fits in my hand perfectly. I have the black one & the white one. I use the white one because all my things are black & I'd lose my phone when I had the black one on.
