I saw a similar problem in the HTC Hero forums, without a concrete answer, but I wondering if it were a problem for Galaxy S users as well. Basically, I want to use the Gmail app that comes pre-installed. I have my Accounts set up to sync everything Google related: contacts, gmail, calendar, and picasa [which I don't use, but whatever]. I Don't want to use the Email app [the one with the @ symbol on the icon]. The problem I'm facing is there appears to be a fairly large delay between receive the email on my computer, and receiving it on my phone. I have Wifi Sleep set to Never, and enabled Notifications on the Gmail app as well. What am I missing? edit: I should probably note that it was working yesterday when I first tried it. I received emails on my phone instantly.
