Refurbished iPhone 4 (left) with yellow display

Apple replaced my iPhone 4 yesterday because of a malfunctioning select button. The replacement device is a refurbished iPhone 4. Unfortunately, it has the yellow display problem that many people complained about when the iPhone 4 was first released. I apparently have one of those that was returned. You can see the yellow display problem in the photo above.

The refurbished iPhone 4 I was given also has what appears to be an older model number, MC319LL, compared to the phone on the left (still running iOS 4.x) which is a model MC610LL.

I’m going to make another appointment at the Genius Bar to have this phone replaced.
