Well, here's my opinion, they type certified it as a GPS capable device. They then REMOVED the real antenna (conspiracy theories?) and replaced it with a shorting loop which is almost a exact match. It's held on by 2 screws, same mount as the real one in that pic. So it's potentially possible to replace with the real part if we can order them, or for that matter, we have the fcc pic, we could duplicate the part ourselves and replace it!
Here's the catch, we need the radio image at minimum from that fcc model, or a real gps enabled model. I would encourage others with verizon, alltel etc to take pics of this part and post if it's any different. They wouldn't type certify it unless they are selling it to someone... Perhaps a korean model!?
EDIT: I've removed the antenna blank from my phone and verified, it is nothing more than a blank, furthermore, we are missing a part of the LNA circuit as pictured at the fcc link:
