Pull mail: You need to connect manually to your mailbox via internet and then sync the mail box. A copy of the mail is pulled from the mailbox to your device.
The only services that provide push mail are Blackberry and Windows Mobile 6.0 (and higher). This is where Blackberry and WM-6 devices score.
But push mail does not happen automatically. You must sign up for the service and the service provider should be providing that facility. And finally, your mail service (your office mail - Exchange or Lotus Notes, or Gmail/Hotmail/YMail) must also be agreeing to the same.
All Blackberry/WM-6 devices sound an alert (just like SMS) when a mail is received. My office is willing to provide me the Blackberry service but I must invest on the device cost (VPs get the device also from my employer).
In India, Blackberry services are provided by Airtel, Vodafone, BSNL, and iDEA. I do not know about other mobile providers. Someone please update.
