I Am Having The Same Problem Everyone Else Has With Their Iphone Screens... My New Iphone 3g-s Has A Dull Yellow Tint Compared To My Old Iphone 3g Which Has A Deeper Black(nicer Look)... But I Think I Know Why--- They Both Have The Same Battery But The New 3g-s Has A Better Battery Life According To Apple And I Think The Dull Screen Consumes Less Power From The Battery Than The Old Iphone 3g Screen Which Looks A Lot Better And Makes Things Look Alive!
