Was just at Best Buy (isnt that how all of these thing start......anyways) and they have dummy phones and large foam board displays for the Nexus S 4G I took some pics of the dummy the battery door is different then the Tmo Nexus S it is a smoked chrome with black dots looks very nice. Check the post about the back being textured (which it is not by the way)
Also the dude told me that they havent starting and device specific training and the dont have any phones in yet.
