Is their any difference between IMAP and the Push Technology .mac uses? I currently forward all my email accounts to my gmail account. I do this so I can log in to my gmail account anywhere to get my email. I have a .mac account and I am buying a new iPhone when they come out. My question is should I use the gmail account still to get my mail on the iPhone or forward all my account to my .mac account so the messages get Pushed to my phone.
