how does this work with IMAP email (specifically Nokia Messaging pushing to a gmail account)? I'm having a bit of trouble visualising what happens when data is being puhed to the n900 by an external mail server at arbitrary times?

If the app has autoDisconnected all connections (2G/3G and WiFi) due to inactivity and a mail then arrives in my gmail acct, will it still get pushed & received immediately, or would it need to wait for a reactivation of a data connection being done (manually or by a widget or whatever) on the n900?

Sorry if that is a dumb question but I rely on push email and I assume it needs genuinely "always on" data connection for it to work optimally - very nice app regardless though :-).
