May be I am missing something, but so far I do not understand the difference between push gmail which is set up using Exchange and what I have used so far - IMAP.
In both cases I am getting a badge and a sound.
Also I am a bit confused on the settings:
I have turned on PUSH, but below it says fetch - every 15 min, 30 etc. I am not sure how to properly set up push gmail - does the fetch still have to be set say for 15 mins?
It is my understanding that if you have push enabled, you don't have to fetch anymore. So, leave fetch off and keep push on.
