One of my users will be receiving a Blackberry soon. I have never dealt
with wireless access before.

What are my options for connecting the Blackberry to the Groupwise system?
I know that I can purchase BlackBerry Enterprise Server for Novell
GroupWise. I also know that I could just have the Blackberry periodically
pull down email via POP3. Are there any other options?

Also, if my user wants access to his address book, calendar, etc., would
we have to purchase Enterprise Server, or can it be done some other way?
