To Do's in Calendar app for iPhone

[ftfaria]

I saw on the Apple website that there is a new button on the bottom right side of the Calendar app in the new iOS 4 for iPhone. Maybe they implemented the To Do's in the app. Does anyone know if it is really the To Do's like the calendar app on the Mac OS X?

Thanks.

That button is for invitations, not "to do"
