Well, I just had my iPhone replaced due to a faulty black piece. My new iPhone has a grid of tiny white dots all over the screen (mostly visible in low light/black background). From what I understand many people have had this issue and it seems to be limited to the 7-series lcd screen. So my question is this...Will Apple replace my iPhone?? And if they do, will they merely send me another phone which could also have a defective screen, or will they make sure they send me a 5-series, or at least a 7-series with a flawless lcd?? Thank you for your help!
