> And I have to ask – why not?! Apple has a stranglehold on their ecosystem just like Blackberry did. They could easily require any new vendor to integrate into their own messaging app, or require apps to use a unified messaging framework which their app could pull from. They could kick out any app that didn't play by their rules. The reasons for not doing this are almost assuredly either legal or business conflicts, or clinging to ideals like the screen wouldn't be as pretty. There is no technical hurdle.
