Do stop me if you've heard this one before... but customers are complaining that their shiny new iPhone 4Ss are suffering from a yellowish screen.

Discolored screen, scratches on the back: anyone for an iPhone 4?

The awe-inspiring beauty of the new iPhone 4 is looking a little faded, with reports of yellow patches on the screen and an easily scratched casing.
