It's a good question. I'm not really sure. My guess is that since the 3G and 3Gs had plastic backs and they didn't exhibit this "buttered bread phenomenon" that the iPhone 4 type design with a plastic back wouldn't either, but you never know. Of course I would prefer the back be curved aluminum like the iPad 2, os not sure if this changes the outcome or not.
