I distinctly remember reading article that they fixed this on later production runs with some sort of coating. Wasn't the white iPhone 4 delayed for this?

There some projects to realize low-cost, short turn-around-time LSI fabrication at slightly old process, such as 1um, in Japan, whose name is Minimal Fab. This will enable the (commercial) LSI fabrication service at a few hundred USD cost and 1-week TAT. I believe this a revolution similar to that happened in PCB world in ten years ago.
