A firewall is very useful on BlackBerry for high security environments, because BlackBerry uses government-quality security. (Encryption, etc).
Firewall is mainly used to authorize/de-authorize outgoing connections from third party networking applications, such as Verichat, WebMessenger, Reqwireless, etc. You get prompted whenever an outgoing connection is made for the first time from a 3rd party application.
Security Tidbit Facts: In fact, it's possible for BES users to remotely kill their BlackBerries when they are stolen. A password can be forced to be entered into the BlackBerry every 15 minutes too -- and if the wrong password is entered 10 times, the BlackBerry destroys the contents of its memory (lobotomy feature). There are signed API's which means you can't write a program that intentionally reads the addressbook, without that $100 signing key from RIM. Nearly impossible to write a virus for BlackBerry... And attempting to disassemble a BlackBerry and reading the flash chips directly, just yields useless encrypted data if you don't have the password. (Content Protection must be enabled in Options->Security) ... Even CIA was impressed at the BlackBerry security.
