I really wish they had any information about the technical details behind this. Do they mirror your email on their exchange server or something?

They don't mirror your mail, you receive a pushed mail on the msgpush account telling you new mail has arrived. You still have to read it on your regular account

What protocol do they use on the msgpush account? Push IMAP? Something else the iPhone supports?

no they kinda fake exchange (I don't know the technical details behind it) ,since push IMAP is not supported on the iPhone.

Yes, "something else" the iPhone supports in OS 3.0, which is "push notifications".

These is a background notification service any iPhone app can use that can show a text message on the screen and update a counter (aka "badge") on the icon of an app that isn't running.

Push notification in iPhone OS 3.x is not to be confused with Exchange or ActiveSync so-called Push email.
