iTouch and Calender

Guys,

I'm asking this question on behalf of a friend who wants to get an iTouch but he uses Windows , (Sorry I know I've told him to get a mac).

Question is what does the calender on the iTouch sync with when using windows?

We can get our work rosters by iCals, is there a calender which windows can use which will also use ics files?

Cheers

I believe you can sync it with Outlooks Calendar as well as Googles.

Thanks, we've set up a Google calender, but how does it sync with the iTouch?
