Don't palm it
I don't have an iPhone, either old or new. AT&T is not available where I live. But I do have a Blackberry Storm2 provided by my employer. It is of a similar style of course. When I hold it up to my face to talk, I don't "palm" the corner. I just hold it with my fingers and my palm doesn't touch the corner at all. So I am assuming I would hold and iPhone in a similar manner. This seems like a non issue to me. Even if it is as bad as some are saying, the solution is simple. Don't wrap your palm around the lower left corner. There, problem solved.
