I know this isn't the right thread but since the one that was started is locked...
As well as having a silver nick in the black band, very small admittedly but we're two days into ownership here with no knocks - the phone also exhibits a noticeable yellow/green tint.
Here's an iPad photo so not good quality but shows what I mean (looks notably worse by eye - I also calibrate screens as part of my job so might well measure the output in the office tomorrow).

This is compared to my iPhone 4 which may be a touch blue but closely matches my iPad 2. There have been quite a few times I've felt the colour as "off" on the iPhone 5 whereas I never did on the 4. I know how a properly calibrated screen looks, I'll post lightmeter measurements if I have time tomorrow and if there's an appropriate thread, not expecting this to go over time, more likely just grow to accept it as people do.
The iPhone 5 for me is a mixture of nice upgrade and niggling disappointment in Apple's standards.
