Is your blackberry a work or second hand blackberry? Could be the last owner was an AB user too. Do you know any other ABer's in real life who may have borrowed your phone?
If you've posted as that, your blackberry browser is logged in as that!
I can see when you cock-up your passwords and I can tell when they don't match your real ones. Everything is encrypted, but I can see patterns of problems/issues in the encrypted strings.
