I just got the Iphone 4 today. Very nice and sharp but I find the screen has a slight yellowish cast compared to my 2 year old Iphone 3G. The older model seemed to have more contrast between text and white background. This new one is more washed out, though still very crisp. Photos look fantastic. But on Google News, for example, the screen feels less contrasted. I think the older model 3G veered toward a bluish tint to the white and I got used to it. Anyone else find the default background hue a bit toward the yellow?
