For testing purposes (license check) i have to make an account under account & sync settings in the emulator (2.2).
But instead of getting a choice between "corporate" and "google" I get directly a window for
adding an Exchange account.
I put in my email and password and when i press "next" I get a window with
Domain\Username and password entry.
When I leave it to the default settings i get : "Unable to open connection to server"

What do I have to put in there?

If you are trying to add a google account, here's what you have to change in order to make it work:

Domain\Username: "\<username>"
Password: "<password>"
Server: "m.google.com"
