Gmail on iPhone

I´m wondering, how you guys set up Gmail on your iPhone (or other iDevice). I had it set up with an Exchange account, but since this doesn`t work anymore, i have to look for an alternative. Currently I use the Gmail app, but I would much like to use the Apple Mail app again, but without push, it´s not doing it for me. So how do you set up Gmail, or which apps do you use?
