I got my new iPhone 5 black and the corner is scratched?

Does anyone else have this problem? Can I get a new one! Really upset! Does the white one have this problem?

From the iPhone 5 problems revealed on the Internet, we can see the back and the corner is easy to scratch, especially for the black one. I have heard you can change a new one from the Apple service center. You can have a try and contact the Apple service.
