PocketMac released version 4.0 for the Blackberry and now supports iSync to the BlackBerry® Pearl™ 8100™. It lets you load new applications and synchronize email, contacts, calendar, tasks and notes with popular Mac applications, including:

Mail.app Email
Entourage® Email, Contacts, Calendar, Tasks and Notes
Address Book Contacts
iCal® Calendar and Tasks
Now Contact®/Now Up-To-Date® Contacts, Calendars & Tasks
Meeting Maker Contacts, Calendar, and Tasks
Lotus Notes Contacts, Calendar, and Tasks
Safari Bookmarks (One-Way, Mac to BB sync)

It’s available now to BlackBerry customers as a free download.

It looks like this gamble payed off. I’ll let you know how it works when my Pearl arrives. It seems they are backordered through T-Mobile. No word on when to expect shipment.
