I had the black iPhone 4 and I ended up getting iPhone 4s in White - one thing I am noticing is that the 4S screen is brighter but lighter...the iPhone 4 is darker but it shows the color more and brighter when the 4s is brighter which dims down the colors a bit from the brightness. Is that a good thing or normal? It's weird, I think I prefer the colors to be more colorful if that makes sense. They are both set at the same brightness as well.
