I am looking to see if the "green spot" that appears in iphone 4 photos under fluorescent lighting is in every iphone 4, like some are claiming, or not. Some say its a white balance issue, which I would expect to be a uniform color change, like the yellow tint issue, but this circle always in the middle of the picture. I was wondering if anyone has taken two or more iPhone 4's and taken a picture under the same fluorescent lights and seen a phone that has it and a phone that does not. It can be quite annoying when it looks like the color is slightly different around the edges of the picture. It can be seen in normal pictures, but it is better demonstrated on a white or light wall under fluorescent, both linear and compact. The compact fluorescents have a habit of making some phones have a severe yellow tint as well as the green spot. If you have compared and seen iphone 4's that have it, and those that do not, please share, pictures for comparison would be good as well.
