I don't understand this comment. If it's not a deal breaker for you (it happens to not be for me), then cheers. However, a part of the selling point of a phone is aesthetic. Some may feel that the light leak effects the aesthetics, therefore the phone is not the value they bargained for, so back it goes.
And to this thread in general (and actually message boards in general), I don't understand all the hating. All the OP did was share an experience. Why do some people feel the need to flame, insult, question how many phones he returned, why, etc. He wasn't looking for that.
