I, among many of you, are hoping to pick up a new iPhone on the 11th. My only worry is that the white one, which is the one I want, might discolor over time. My friend used to own a white Samsung d807 slider and said that it became slightly blue over time, and I am sure many of you remember the old MacBooks that turned yellow from white over time. I would much rather have white, but I really don't want it to discolor, I take good care of my stuff too. It will likely be uncased for awhile. Thoughts?
