All phones and all RF antennas have problems when large sacks of water surround them. I don't think anyone is arguing that point. It's a straw man that Apple set up to attack.

That Samsung phone video doesn't show anything other than the fact that the bars go down when she covered half the side of the phone with her finger. You and I both know that bars don't mean shit. I've often had max bars and no connectivity to speak of, and zero bars and perfectly fine connectivity.

Videos of the iPhone clearly show a light touch on the iSpot causes data transmission to come to a halt. (One example of many.) This is, again, clearly a different issue.
