Blackberry Ical Sync

How do / can I synchronize my Blackberry with a working computer is a Mac for my home computer is a Mac?
OK, here is detail. My computer at work is a mac. We use a BlackBerry Enterprise network. I wireless sync entourage to have MS on a Mac at work. I use iCal at home. I I would like to synchronize calendars, work and home. They told me to synchronize my home computer could move the process of synchronization with my work computer, especially since I'm using two different e-mail and calendar programs. Is there a way to synchronize or transfer my personal case of lime to my BlackBerry? Getting a iPhone is not an option. Blackberry is what gives my work and that is what I have to use.
Manual synchronization can cause synchronization Wireless to shut down. Why not export the data from your calendar in a personal e-mail to your e-mail at home. You can import the data into iCal.
