One Mac and two different iPhones - how?

[oysteins]

I have two iPhones, one for me and one for my son. I sync both on my Mac. Problem is that he gets both my calendars and address book on his phone. How can I split it, without making him another user on my Mac?

each phone can synch seperate calanders

when plugged in, go to the data tab and adjust accordingly
