If this doesnt work, then try doing it without a password. My unit doesnt have a password on it.

Your Blackberry 8220 needs to be unlocked, have an AT&T SIM, AND you MUST have a Blackberry data plan.
Change the TCP setting to AT&T’s settings; Options>Advanced Options>TCP
user name for APN: WAP.CINGULARGPRS.COM
(use caps as shown)
Update your BIS account at, BlackBerry Internet Service with the 8220 Flipberry PIN and IMEI.
Setup Wizard only allows the option to setup BES email, which I don't have, The Email Setup icon is also missing, Not found in any of the folders.
SO you need to setup emails from your BIS account. After you do this move on to the next step.
From your BIS account web page click "Send Service Books" and the ability to send/receive emails and the service books for MMS will be installed on your Flipberry.
I still can't setup emails for BIS on the Flipberry, but this is a viable workaround. MMS works great for me after doing all of the above
