This is obviously a subjective question - you're asking us to guess at Nokia'a business strategy.
However, my own personal guess is that Nokia won't port Qt to the iOS, but the community will (in fact, the work has already started). I suspect that a port to android is much easier than a port to iOS, and will happen soon enough.
But then again, that's just a guess.
Why not put your energy into helping port Qt to these new platforms?
