As of now, my reasoning is that people with iPhone are less likely to use Windows and MediaMonkey (and more likely to use OS X and/or iTunes). However, if enough people want this, it might be possible in the future.

I'm sure quite a few of us have corporate iPhones in spite of our preference for PC's
