I want my iPhone to check for my Comcast email only once per hour. I have Push turned off, and the selection for Fetch set at one hour. I send test emails and find it is pulling it within just a few minutes, not every hour. Is my iPhone whacked, or is there something I am missing? Thanks.

All depends. The Test "pull" may have occurred and now every hour it will "poll" the comcast server for new e-mail. as an alternate use http://att.my.yahoo.com/ it provides "Push" e-mail.
