Yes, the original back cover is completely shattered after a fall. So had a new forth but do not be fooled by the offers "Original" you. There are no original back cover, this gets you incl. The exchange for EUR 29 in the Apple Store. Or you can be served a copy of, like this one. Basically, the back cover of good quality and fit. The surface was protected and previously not been in use. A limitation on the camera's eye, I could not tell. The height difference is really minimal and is hardly noticeable not until it looks simply none.
However easily comes across that the wrong screwdriver has by lying. In my Iphone 4 are cross screws and not those little Apple Torx. The tool is therefore useless and it has to serve the fine mechanic box Cross. Annoying for buyers who have no other suitable tools at hand. Nevertheless, due to the price and feel a recommendation.
