Hmmm, it seems that the iPhone 4 isn’t exactly free from problems, similar to the HTC EVO 4G in some aspects, with problems concerning its screen as well as antenna. As for the former, it seems that the dreaded yellow spot problem will disappear from the iPhone 4’s display after a while, and some smart aleck on the AppleInsider forums seems to have come up with a pretty interesting (and valid) reason.
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.
What do you think? Will such niggling issues prevent you from going ahead with your iPhone 4 purchase?
