The lack of response from Apple is fairly spectacular.
The problem is, if they admit a product problem, that could precipitate a full recall of affected iPhone 4Ss. The fault is not a danger to users, and I suspect that would be the only case in which they would make any such statement. They are watching the bottom line.
Perhaps like the poor signal on the 4 owing to users actually holding it - unlike the human free test facility where signal is tested at Apple - they will issue the equivalent of the 'bumper'. Perhaps a blue or violet acetate filter to lay over the top of the yellow screen to neutralise it. 😐
I'm still on my first 4S despite four yellow replacements, two 'replacements' a week apart at the Covent Garden Apple Store, both just as yellow and I walked out both times with my original iPhone 4S, although in their now familiar way, the 'genius bar' messed up the paperwork and recorded the swap as having happened....
....which in turn messed up my swap I tried to arrange direct with apple, as they now had the wrong serial registered to me - so another few days delay whilst that was reversed.
...then I received two further replacement iPhones within a week, both of the screens just as yellow, the person arranging the swap became unobtainable for days - she had 'been away for a few days', and when that happens at Apple, apparently noone else deals with problems, that was on the 30th Nov, yesterday another one arrived, it too is yellow.
Very boring waste of my time, luckily Apple employees get paid to be so inefficient.
On the Plus side, if this was a LaCie forum about their drives, or a Crucial forum where they claimed 100% compatibility for their M4 SSD drives in MacBook Pros, the post would have been vetted and never posted on their site - fact, that's what they do. Fair play to Apple, at least they leave this potentially sales damaging stuff for all to read - that I do have respect for, even if the rest of my iPhone debacle is less admirable.
