I'm trying to get my Apple computer and my iTouch to check mail at the same time, to the minute of the real clock so that the new mail shows up on both simultaneously.

I have the iTouch's push set to 60 seconds by editing the .plist
And I have my powermac's Mail.app set to check every minute.

But they don't check at the same time. It looks like they're set to a timer that changes according to WHEN you check the mail.
Anyone have any ideas?
