This post is a response to a debate about the Razr antenna location. Here’s my educated guess.
The parts shown at the top are listed as the antenna cover and the antenna itself is assembled in the same space over the speaker assembly. These parts are from CNN as the links show. The external antenna connector would seem to confirm that the antenna is located down at the bottom of the phone and not the top.
The antenna is down low, just another reason why this phone is so different from the rest.
