I have an iPhone 4 that I dropped and the screen completely shattered. Apple swapped it out for a total of $160 but after the phone restored, I noticed that the screen had a yellow hue rather than the blue/white previously. After two further swap outs Apple tell me that the screen is 'within manufacturing tolerance' and there would be no further swaps. I don't understand how such a difference can be acceptable (to them) and that I have no right to disagree with their decision. I accept that life will not end with a yellow tinge and a yellow tinge is better than a smashed screen but I am disappointed. Seems if things are difficult for Apple then their standards slip and their famed customer service really does only go so far. Has anyone been in a similar position and gotten anywhere with their issue?
