I searched but didn't find a clear answer with newer builds.

The website says it supports Exchange but does it support multiple Exchange servers like the Pre?

I have several Gmail accounts and one Exchange 2007 account and the ability to manage all of these accounts from the N900 will be key for me.

I'm only concerned with email, calendar and contacts.

I could live with at least one Gmail account synced and one Exchange account synced (email, calendar, and contacts) leaving the remaining email accounts on POP/IMAP.

Do any of the N900 testers have such a setup?
