Remember that annoying bug that causes a blue tint in the center of photos? It looks like it may have been fixed in the new version of iOS that is running on the Verizon iPhone 4.
For many people running iOS 4.2.1, there is a blue tint in the center of images - most notably of subjects that are white. There have been mixed reports of the lighting situations that cause it. For some, it's only in the presence of fluorescent lighting. For others, it's only when using the flash, and for the incredibly unlucky, it's for all lighting scenarios.
