Ok, so I hadn't seen this question answered in either of the email threads so I figured I post the link because it seemed to be something several people were trying to figure out.
The link provides you with instructions on how to set up Gmail through an exchange server so that you can get push email in the HTC Mail app. I obviously can't be 100% sure this works, but the folks over at XDA seem to think this is the solution for the Desire. The instructions are for a Windows Mobile Device, but all of the information you need to fill in inside the HTC Mail app should be available at the link.
Hope this solves some push email problems on Thursday (or Wednesday for some of you lucky ones)!
