The new Connector they launched today will give you some fairly high-quality results. Emails sent to Gmail aren't true push, but they'll show up within 60 seconds.

Google has been public about plans to get this feature out the door since May, but it's been a long time coming. Since the company decided that Apps was something they wanted to sell to enterprises, lack of integration with BlackBerry Enterprise server has been an impediment to making that sale. Now that's changed.
