My iphone 4 color temperature (screen tint) has a slightly green/yellow push. My ipad has a warmer red push. I prefer the color on my ipad. I understand LCDs can vary greatly from unit to unit, but it is also possible that apple has chosen to calibrate the iphone displays differently from the ipad displays. Do all the new iphone 4s share this characteristic? Could anyone with an Iphone 4 and an ipad compare? If no one has the slightest clue what I am talking about, I will try to post a comparison picture when I get home.
