Even if Apple allowed 3rd party vendors to make IPhone OS compatible phones, Android would still be free and Google would still push it as hard as possible, so the competition would still be there (which by the way is really good). Also, it's not easy to beat "free" from the vendors' perspective.

I think the iPhone will continue having a significant market share and I think Apple will continue innovating. In the meantime, the Android market share will grow, possibly beyond the iPhone share, but I don't see why it's necessary to only have one winner that takes it all. I think both companies, along with RIM, will do fine
