I really don't think it makes sense to say that Bing is better than Google. It seems to be a decent engine, but they haven't published their algorithms and thus we really have no idea what's going on behind the scenes. Google, on the other hand, has refined PageRank for a while and I can say with certainty that the math behind it is pretty clever and makes a lot of both intuitive and mathematical sense. Also, Google didn't buy off everyone and his brother for 10% market share. Honestly, if Apple seriously goes down this path it would probably be the worst choice they've made about the iPhone since slaving it to AT&T's botched network, but it might just be like letting the music labels get variable pricing for songs on iTunes. We got DRM removed and some cheaper songs, Apple looked good for ditiching DRM, and -surprise surprise- no one bought the 1.29 songs. Could be an easy way to get the phone further subsidized, and then have 99.9% of the userbase go through an extra step during setup to reconfigure the search engine when they buy their new, cheaper phone.
