Serious question. Every time I exchange my iPhone, which has only been 3 times in one visit, I feel like I open up the possibility of getting a device with dead pixels, trapped dust, factory scratches, etc. Plus, I'm kind of just getting used to the yellow-tinted LG LCD, as annoying as it is though. When I was last at the Apple store, I swapped my phone out three times and all three new phones had the same issue. Eventually the guy suggested that I just check back in a few weeks and hopefully then the store would have a different shipment of iPhones in.
