Ok so I was at the apple store in the Sco for an hour and got 3 replacements due to various problems each had. I thought I had finally gotten a good one but when I walked outside I noticed that under the sunlight the home button has a blue-ish tint to it but inside it does not. I tried showi g a genius and he looked at me like I was crazy, anyone else had this prob? Should I try another apple store for a replacement?
