Looks a heck of a lot like the iPad application (which is good), has event invitations (which is great), but not even a hint of To-Dos (which is ridiculous - how long have we been waiting for minimal support for those in iOS as well?).
Update: So, they actually were there in the pre-beta version, although I can’t check the beta yet and they’re not mentioned in any of the KB articles about it (that I’ve noticed). The question then becomes how do I see them on iOS?.
