Gmail does not support push, atm YMail and MobileMe are the only email services that support it.
The only thing the iPhone supports with Gmail is the auto email setup and contact syncing via iTunes or the MobileMe CP.
not true, you can set it up as an exchange email now on the iphone.

its in the exchange settings on the iphone, you can turn calendar/contact sync off.
settings -> mail -> gmail -> turn contacts slider off
Thanks, still can't see it though, but perhaps I have to set it up as an Exchange account 1st?
