It looks really sharp! I would be tempted to do this someday, maybe when the warranty is up, because I am assuming Apple will no longer honor the warranty since physical alterations were done, or to them physical damage?
I have thought about this and I honestly have no idea. I don't think it should affect warrenty as it doesn't really mess with anything in the phone. I guess they would have to prove that my work would be the cause for it breaking. So I guess it depends on what would be faulty on the phone. Honestly don't know. Hope I don't have to find out! Personally I don't see how this could break my phone =)
