In the "Contact" App, when pressing Menu, there's some options for syncing ... That asks for credentials to add an Exchange account ...(I had no other choice than Exchange).
I don't have network connectivity for the PE here, so I can't go further now...

I noticed that the old email app is still there. Is there a way to get rid of it ? the uninstall button is not available in the settings. Both apps (email and Froyo email) run simultaneously in the background.
