It's not like there's some kind of secret deal or something that limits that number to $12 / phone, it's just that it appears that in average that's how much iPhone users are willing to spend on apps currently. Apple and AT&T have a much larger marketing power than indie app developers. If Facebook suddenly started to charge $0.99 for their app, I bet that number would bump up to $12.70 fairly quickly.
