The cheapest way to do this is to publish your iCal calender to a web server, just upload it via the "Publish" option in the Calender menu and then your boss can merely have that page bookmarked and view it in mobile safari.
Other than that, you can use mobile me which will do what you need but costs $
It will however immediately update your iphone calender and desktop calender both ways
