folks, i`m planning on getting my n900 on tuesday, to avoid stress and time i would be happy if the following very simple questions could be answered:

1. i take it that the email refresh can be set to 20min, 30 min etc., is there an option to get a refresh as soon as a new mail arrives?

2. when the client refreshes, is there a notification of new received emails?

3. are there any other downloadable email-clients that resolve these problems?

4. what changes will the new firmware/update bring?

thanks in advance!!
