Well, I do know about Cingular's 2.0 version, so I am going to try and correlate (SP). The new BIS versions do not, as of yet, allow syncing with MS outlook. You can have your Outlook pull the messages off BIS WebClient, but thats about it. Since your not hooked up to a BES or Wireless Sync program/application, you wont have that luxury. Hopefully, in newer versions, this will change.
