the rf stuff is pretty complex from what I understand. I think the iphone has around 7 antennas in it (wifi, edge, 3g, gsm, etc). I somehow doubt 'just adding' another antenna is a trivial matter, an expert would probably be able to tell you better what it takes to balance quality/interference with so many radios in close proximity. From what I know about how they work, I'm guessing they've tried out all kinds of stuff including putting in a radio, and probably decided to cut it.
