With all the recent iPhone 4G leaks, we more or less already know what the phone will look like. Now it seems that manufacturers are also confident enough to start churning out iPhone 4G protective casings as well. Pictures of iPhone 4G casings have started to surface in a variety of colors, and you can see that it’s noticeably shaped like a rectangle of sorts, instead of the curved design of the current iPhone models. The additional space for the camera flash can also been seen at the back of the case. Are you planning to buy a protective case for your iPhone 4G when it’s released, or are you quite happy to let your iPhone run around naked?
