Innovative Mac mobility software developer Pocket Mac has developed software to let BlackBerry handhelds work with Macs.
PocketMac for BlackBerry lets Mac users sync their data between their BlackBerry and Entourage, Address Book, iCal, Now Contact, Now Up-To-Date, and even Stickies. It also integrates with iSync and costs only $29.95.
Once the software is installed, users simply need to link their BlackBerry to their Mac using USB or a Serial Cable. It's also a two-way sync system, that allows you to sync changes in everything from Contacts to Calendar Events to Tasks to Notes.
