Greetings, I know that the green/pink areas in the centre of some iPhone 4 photos are caused by certain types of lights apparently. But yesterday I took the same photo with both a 3Gs and my iPhone 4 and the 3GS had no hint of green/pink. I know they're different phones but is the camera completely different? Obviously the 4's camera is 'better' but I was just surprised to see that the 3GS had no issue at all. This is my third iPhone 4 and all three have had it, I've not minded it so much until I noticed this. Does every iPhone 4 user have this issue here? Do any 3GS users have it?
