Blackberry's website has a sync program you can download, for me on my imac and macbook its called 'PocketMac for Blackberry" Once downloaded it makes an icon for syncing phone numbers and calender. I did a couple of years ago and didn't know where it went but found out accidentally that all my contacts on my Blackberry are in my Address Book on the bottom row, some of my calendar events are there to 😀 WOOHOO who knew, haha.
Its making it apparent that should work quite well with another Mac product, though if my iphone doesn't do the basics as well (make phone calls, text & email), (I'm also demoing a Nexus 1 for the next few weeks) there are other options and Blackberry may get another look depending on the Nexus 😎
