A 64-bit chip in that phone is a gimmick. It has what, 1 or 2 gigs of RAM? No where near the 4GB limit of 32-bit. And developers aren't going to rush toward 64-bit programming when the money is made in catering to the 32-bit masses. Apple has always done it this way, they make things and then attempt to force consumers to think they need them, instead of listening to their customers needs and making a product that fits them. If they did the latter there would be a 5" iPhone by now.
