I'm wondering who has a "light leak" coming from the plastic back of their iPhones. This is different than the light leak many have had on the front of their phones. In the dark, my white 16GB has a great deal of light that radiates through the plastic. It's only noticeable in the dark, but to me, is pretty bright. It's almost like the dye used in the plastic wasn't evenly applied, allowing light from the screen to penetrate through the back. I've had this on 3 3Gs, all white. If you have had this issue as well, please indicate what color your iPhone is and the week it was produced if you know. I had a unit replaced because of this, and that replacement has the same issue. Maybe I'm being overly critical, but I don't think its too much to expect this not to happen.
