I surprised people aren't talking about the lack of Push for iPhone Apps. Apple promised it would be in this update and was until about a month ago when it was removed from beta. Yes the phone supports push email, but say for instant messaging with Mobile Chat, it logs you out when you close and App. Push would have allowed you to still receive IMs when not logged in. Are we positive its not included as promised?
They never ever said it would be in this update. They only said it'd probably be available in September. Last I checked, there is still two weeks + left in September. Even if it doesn't get released before the end of the month, they didn't pinky promise or send everyone an email saying that it would def be available. It is not hidden in 2.1 either. If it was there and functional, I'm pretty sure they'd let everyone know.
