NWR: need blackberry help!

so my office's email server has changed, and i need to change it on my blackberry (a tour) so i can start getting work emails again (it is already set up but is now wrong because we went from imap to stmp).

does anyone know how to change the settings (without having to input it as a new email address)?

Go to messages
click the BB sign
Go to options

In there I think reconile settings
