iPhone 4/4S different display qualitys

Hi everyone,

I`m on iOS since version 1.1.3. Got my iPhone 4S yesterday and know these stories every year, of yellow tinted screens. Never had any issue with it. Until today. Compared to my iPhone 4 (got it right the first day it was released in switzerland) the screen from the iPhone 4 looks blueish and the one from my iPhone 4S looks something like yellow.

So I made some Pictures with my Canon DSLR. The iPhone`s were at full brightness with auto brightness off. Both devices running iOS 5 and have the same apps installed and the same data on it.

Always on the left side, the iPhone 4S with the more yellow tone and on the right the iPhone 4 with more blue tone.

Why does apple provide so different screen colours, no QC and recalibration of the screens? I buy apple because of their high quality products but this is not high quality...

And I`m not the only one who has problems with the screen colour, its like a gambling to get the "right" colours in their iPhone.
