What is the difference between fetch and push on the iphone?

Question

I just downloaded the new 2.0 and I went to my settings and I don't know what "Fetch New Data" means? What does Fetch and Push mean and all that? I don't know the difference between the two or even if there is a difference

Answer 1

Fetch means the iphone will check when you tell it to and every 15, 30, or hour. Push means that youre iphone doesn't have to wait battery to check for new mail because the server just tells it when it has new mail. Push can only be used with certain email  services that offer push mail such as yahoo or mobileme.

Answer 2

most likely the email app...

Fetch it will get it when you ask it to... Push is when it goes to the server, it will push it to the device.
