Has anyone used a wallet case with their iPhone? I'm considering upgrading from my 4S to a 5 and I've been looking at cases that combine wallets and the phone itself. So far, the one I like the most is the Little Pocket Book by Pad and Quill. Does anyone have any experience with this case or company? Perhaps someone here has a better alternative to wallet style cases? I want to completely eliminate the use of a conventional wallet. Feedback and ideas are appreciated. Thanks!
