Hi All I got my 64GB iPhone from the Apple store in the UK on launch day and I have noticed that the steel band had some shiny marks on the it. Its about and inch and a half lower that the volume keys. This is my 6th replacement on the same day as the others had 1 or more dead pixels. Plus there was one with a chip in the steel band and one with a small tiny hole in the steel band.... I am thinking to change it as I like my phones mark less but I prefer them with out dead pixels..... too..... so it s a chance... What do you think... are the marks on the steel band common.
