Me, along with another member "AndrewR23" have been through many phones, all being yellow.
The past year, Apple's QC has definitely slipped. If you walk into any Apple store, you'll notice how bright and crisp the displays ALL are, while you have a dingy yellow.
AndrewR23 has had a genius open
40 iPhone replacements before finding one with a good screen. That's insane. Going to the store will get you no where. The iPhones in the black boxes are re manufactured. The chances of getting another yellow screen are extremely high, call Apple Technical support, and ask for a senior adviser. They will put a $600 hold on your credit card, and overnight you a new iPhone. That's your best bet if you want to get rid of that screen.
I have come to the conclusion that it's either extremely bad QC, or different screen suppliers. The "give it time, the glue needs to dry" excuse is *********. It doesn't go away with time. Trust me.
If you notice, last year
almost all the AT&T iPhone 4's had the bright blue screen. As demand increased, the production needed to as well. My theory is that they started to use different suppliers, or were rush manufacturing the phones, causing bad quality control and crappy quality screens. It's sad really, this problem BETTER be eradicated by the time the iPhone 5 comes out, or Apple's in for it. It's pathetic and annoying. I'm on my third replacement, and I'm going to call later this week to have them ship me another one. Don't let people tell you it's OCD or something. It looks like crap compared to other phones. It's extremely annoying to have this type of screen. The selling point of the thing is the super awesome "retina" display. Well it looks like crap. It seriously better be fixed when the iPhone 5 comes out
TL;DR Your screwed
