It seems that the screen discoloration issue with some new iPhone 4s may be caused by a bonding agent that hasn't fully dried.
According to an AppleInsider forum poster the issue will disappear over the next couple days as the glue dries.
Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow "blotches" will disappear.
How do I know? I was involved in pitching Z-6011 to Apple.
MacRumors hasn't been able to verify this claim; however, at least one of their posters had their spots completely fade away.
I had major yellow spots on the bottom corners of the iPhone 4 this morning when I received it (as shown in the other thread) and as of right now they have COMPLETELY faded away. I have no idea what caused this but it happened. So keep an eye on it over the next day or so if you have the issue. . . It just seemed like the more I used the phone today the more it faded. It's really odd but I'll take it.
