Thanks for all the detailed info in the replies - much appreciated.

Sounds like the device will allow me to send new emails "From" any of my configured accounts, and automatically replies to emails that I receive at a given account will be sent "From" that account's email address. Basically people I'm exchanging emails with won't notice any difference.

The only thing that doesn't seem to work is replying to mail sent to one account "From" another account. The only exception being the ability to send email from the XXX.blackberry.net account with a "Reply-To" address that's a different account.

And the issues with syncing folders / subfolders in some configurations, but that I can live with.

That'll work for me ... now it's time to start working on those thumb exercises.....
