What is the Blackberry account?

I don't know if this is your situation or not, but if you are forwarding to the carrier supplied BB address, that is a bad idea. First, if there is ever an outage (and there have been a few lately) you are totally without email since you can only read it on the BB. Plus, since you don't actually own the account, it can change, as int he case of cingular going to ATT and you can't take it with you if you change carriers.
