So, I just noticed one stuck green pixel (only on black screen) and one dead pixel on my 1 1/2 month old iPhone 4S. I had to exchange my first iPhone 4S for 2 stuck pixels (not sure if any were dead). I also have seen people that have returned several iPhones for the pixels also. So are the pixels that uncommon? I really don't want to replace if it is going to take a few tries to get one without screen defects. They are barley noticeable but still bother me a little bit.
