However when I turn both on, one comes with a warmer screen (yellowish ) and the other one is cooler screen (blue-ish). Both are acceptable but I am confuse now as to which screen I should take for myself. Please drop me some suggestion. If I stare at the warm screen it doesn't look yellow to me if I get used to it. However, the cooler screen is not bad at all as it look exactly like my black 3GS screen. What should I take into account before choosing which one is good? Should I return one of them?
