So I'm starting to believe that the replacement iPhones are ultimately crappy. They all have the "5K" serial number and I've always had some problem with them. I just got mine replaced last week for cracks in the plastic housing and received a replacement with rockin' light leaks on both sides. That said, does anyone know if I were to bring my phone in with all boxed accessories if they would exchange it with a NEW IN BOX ( Not White Replacement Box ) one? It's just really getting old. Thanks.
