I went to the apple store to see if I could get an iphone with less of the green blob effect. While I was there I looked at every vzw phone and every att phone in the store. As expected all of the at&t phones had the green blob, but none of the vzw phones had it at all. The picture was much more clear under the CF lighting. Is this known? Why would the VZW iphone be any different as far as the camera goes?
