You didn't mention what device/vendor, but for an 8700c (Cingular): Settings --> Options --> Advanced Options --> Message Services
Hit the space bar until the default address appears (or hit the [Alt] key to display the entire list to select from).
If you're on a BES
(BlackBerry Enterprise Server), Desktop
is your Enterprise email (and typically the default).
