Guess Apple forgot about PUSH!

"Push" is working for me and I don't even use mobile me.

I use GMAIL and I actually get emails quicker on my iPhone than I do on my laptop.

My laptop is set for every minute and my iPhone is set for every 15 minutes, but for some reason I always here the noise on my iPhone and I look on my computer and the email still hasn't arrived until a minute later.

That's a bug in 2.1. If you have the iPhone locked and not on a charger, the email won't come in until you unlock your iPhone again.

Here's a short list of good articles:

Understanding Direct Push (MS article)
Direct Push Guide
IMAP Idle

RFC 2177 - IMAP IDLE

And here's that white paper I was looking for before, when talking about Blackberry bandwidth savings over other email / etc implementations:

Push Email Efficiency - RIM vs MS (pdf)

sweet!

So Direct Push works with heartbeats that its the same as the polling the server after n minutes. But this poll is more simple, there's no need to init a newer session on the email server, so network operations are saved.
great stuff.

... I'm running 2.2 but what does that have to do with what I said?

I get a notification on my iPhone immediately when I receive a new email. On my mac, it's set for every minute, and still my iPhone manages to always get my emails first.
