A phone in your pocket now takes place once away. And that's why I looked for a model that the smartphone does not even greater, but is as lean as possible. I've found the SlimCover for Apple iPhone 4 / 4S from Krusell and it ordered me in black. The front cover is made of high quality leather and makes optically correct what ago. And it comes close to all important buttons and controls. To make calls you must not get out, just open the flap with magnetic closure. In addition, the iPhone sits perfectly and securely in the cell phone pocket.
