ICAL POSSIBLE APP IN BLACKBERRY WORLD

I AM NEW TO THE MAC WORLD...CAN SOMEONE PLEASE TELL ME IF IT IS AT ALL POSSIBLE TO SYNC MY BLACKBERRY TOUR TO MY ICAL CALENDAR . I HAVE BEEN LUCKY ENOUGH TO STUMBLE ON HOW TO SYNC MY GOOGLE CALENDAR TO ICAL BUT I WOULD LIKE TO SEE IT ALL ON MY PHONE. ANY SUGGESTIONS OR WEBSITES TO DOWN LOAD APP IF IT IS POSSIBLE!

AND YES I WILL EVENTUALLY BE GETTING AN IPHONE BUT UNTIL MY CONTRACT ENDS I AM STUCK...LOL
