BES = BlackBerry Enterprise Server (i.e., Corporate BlackBerry server)
BIS = BlackBerry Internet Service (i.e., Personal BlackBerry service)
If you have a BES data plan, you can attach to a BES and also use BIS (if the BES policy allows it).
If you have a BIS data plan, you can only use a BB for personal use and cannot connect to a BES.
No longer a BES Admin, but it was fun while it lasted!
