Why reception issue on only bottom left seam?

Ok, we all know about the reception problem when bridging the two antennas at the bottom left seam, but there are three seams total (one on top by the headphone jack and one on the bottom right). My phone is one of the ones that loses reception when held in my left hand, but when I try to do this on any of the other seams nothing happens. This makes it seem that it's not a hardware problem or else I would be getting the same effect on all seams, though not sure about how software could help either.

the seam on the right is cosmetic (not a real seam). not sure why it doesn't happen with the top one, but I haven't tried.

Correct me if I am wrong but didn't the gizmodo leak model not have the right seam? Must of been a late add. And the top seem is not an issue because no one would cover it in normal use.
 
Perhaps it is just the way the 2 "antennas" interact with each other when they are 'joined' together by touching them both? Because the keynote did say that each antenna is used for certain features... like one section being for cell-phone transmission and another for say Bluetooth and Wifi (as an example not totally sure which section is used for what transmission)

That's basically what one possible theory people have put forward says.

By bridging the gap between the antennas you cause problems (that only seem to have an impact on the GSM/UMTS antenna).
 
I just got off the phone with Apple Care and they said I should not touch both the left and right gaps at the same time... I am not sure if that was the issue, but that is what he said. Still playing around with it. :cool:
