I did some extensive testing with mine yesterday. I have a legit AT&T 3G phone with family plan service with the STANDARD iPhone DATA plan.
You must have WAP Push enabled on your account !!
>> I called and confirmed that WAP Push was enabled on my account already.
If you don't have it enabled on your account they will add it no problem. If they ask you why you need it just tell them that you're not getting your PUSH MAIL from an Exchange mail server at your office.
** They will try to get you to upgrade to the $45/month Data Plan for business Enterprise / DO NOT DO IT. You don't need it. If you have to argue with them they will eventually put you in touch with their iPhone tech people.
** They will also try and pawn you off to Apple directly to ' help ' you setup your mail. Again DO NOT DO IT, they can't help you , even if you were having real problems with Push Mail.
Here's my settings:
I'm in California, USA.

I can SEND and RECEIVE 100% to AT&T no problem at all
I can SEND 100% of the time to Sprint, T-Mobile, Verizon
I can RECEIVE 100% from Sprint ( Received all 20 sent to me )
I can RECEIVE 90% from T-Mobile ( Received 18 of 20 sent to me )
I can RECEIVE 10% from Verizon
Verizon seems to be the hard one to receive from. I only received 2 out of 20....
** Important note:
After I installed the app I had several immediate issues with dropped calls and data connectivity. I would have full 3G signal and no data access every few minutes in known good areas. The issues did seem to lighten up but I still have dropped calls where I didn't before. I believe it's the new app making constant data connections and the phone falling back to Edge for a moment in weaker data areas. If you're on a call with 3G and it flips to Edge , even for a second the iPhone will drop the call... so it's not so much the app but that something about it is always trying to make a data connection and when that happens and you're on the phone AND the phone flips to Edge during the call.... DROPPED CALL.
