Dead pixel on my iPhone 4S
iPhone 4S, iOS 5.1
iPhone 4S has full Warranty. Make Genius Reservation and take iPhone to Apple for resolution. A single pixel and an unforgiving Genius may cause some problem. Show the Genius the bad pixel again and then have them show you a display model with the same problem. You will have the problem fixed, most likely with Replacement iPhone 4S with good pixels.
Returned it to the local Apple Store - was given a brand new one! Great service.
