Well, lets start by telling us what you did. But first, did you create a gmail account? If not you need to do that. Did you make sure that the other email accounts you set up have the right email address, the right incoming server and outgoing (smtp) server information and the right password for that account? Do you have data manager>data delivery>background data checked, data enabled. Under Email and Corporate Sync do you have under email delivery data pushed checked?
