I'm new to blackberry and I have a general question. We are considering moving to Blackberry platform for my business, and some folks will get Blackberry's with Data Plans, and others might just get a blackberry with voice features only. My question is for the folks who get a blackberry with just the voice service activated - can that device be sync'ed to Outlook (Exchange) for contacts and calendaring? Or does a device that is used for voice also have to have a data plan and Enterprise CAL asociated with it to be able to sync? Thanks!
