Hey, I just noticed a dead(?) pixel in the upper left corner of my iPhone 5S. I don't know if I should live with it or if I should get a replacement, since I don't know if I'd get either a sealed or a refurbished one. I don't really want a refurbished since it's just a few days old. It's really tiny and you only notice it on black backgrounds... If I go to the next apple store this weekend and show the genius my problem, is it likely that I will get a sealed one ?
