Im in the US chris, it seems what you have to do is:

On n900 click email,
click the email title bar to create a new acct
new acct then next
then you'll have an option to pick a provider, click the drop down box under Service provider, then select nokia messaging, next
then type in the credentials for your email acct, ie. (gmail = yourname@gmail.com
pw=gmail acct password
next then finish

And Thanks Venom, i posted in another thread asking about this a half hour ago. cheers!
