Maybe Apple should just replace the phone of anyone who has this issue, then they can quickly and easily worm out defective stock, as this obviously isn't a universal issue.
You're kidding right? All of these phones have this problem as has been demonstrated in lab tests now by CR and others.
The only 'fix' for this problem is going to be a change in the manufacturing process in which they spray a coating of some kind (teflon, etc) over the external antenna parts to effectively insulate them against being shorted out by user contact.
At that point maybe they can offer to swap phones for people who want to carry them naked and are being affected by this.
For people to continually stick their head in the sand about this issue and claim that their phone or some other magical phone does not have this problem is simply absurd. The only thing you can demonstrate is that you have the discipline to follow Steve's recommendation and 'don't hold it that way' or you have sand-papery dry hands that don't short the antennas out.
