iPhone 4 discoloration
A few readers have noticed a yellow tinting on their brand new iPad 2 screens. The color changes are reminiscent of a similar issue that appeared on early iPhone 4 shipments. At the time the issue was described as follows:
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.
The issue seemed to resolve itself over a couple of days for the iPhone 4 based on reader experiences. With any brand new launch, Apple seems to be shipping the units as quickly as they are manufacturing them, preventing the required time for the bonding agent to set. We'll know for sure in a few days.

One of the things I like about my iPhone 4 display, besides the Retina resolution, is how close the display seems to the glass. It really feels like you're touching the icons/buttons/photos.
It's one of those hard-to-describe things that took me awhile to recognize (after using my iPhone 3G for a bit), but is a hallmark of quality Apple design :D :apple: Like fine stitching or the lining of a coat.
