Genuine white iPhone back?

Now that the real white iPhone is out, does Apple sell parts? Who on the web sells genuine white iPhone back plates?

Yeah, everyone and their mother is selling an "oem" white iPhone back plate. Doesn't mean they are genuine and current Apple part. Too many sellers are selling white iPhone parts before the white iPhone came to market. Not ready to be ripped off yet so I was hoping someone here would know a solid seller selling genuine white iPhone parts from the released iPhone.
