What he was talking about was a system that checks your email by standard IMAP on your computer but with a more frequent interval than the 15 minute maximum on the phone.  It them sends you a SMS (text message) to tell you that you have the email.

While his solution may be pretty simple, its obviously over engineered.  As an anonymous commenter points out, you can just tell your Gmail account to forward all emails to another email account and use the number@text.att.net thing as your email.

This method is actually better because it is push, while the other method is LIKE push.  Plus, it takes two seconds and you don't need to have a computer running constantly just to save your self 15 minutes.

I stated sending an email to my Google Apps account—spencer@netspencer.com from my MobileMe account—spencerschoeben@me.com.

I clicked send and it took 3 seconds to actually send—like it always does.  But then, I head the airplane flying off into the distance and then "ding" my phone alerted me in less than a second.  Now thats push!

It was even quicker than the MobileMe "push" emails.  (Apple no longer refers to MobileMe as push because it isn't truly push—it's pretty quick but not push by definition.)

Also, to prove that this is faster than checking your email every minute—like I think his system does: I get emails via SMS on my phone before they get to my computer which checks every minute!
