A lot of iPhone and iPad users are not aware of the advantages of setting up GMail using Microsoft Exchange. It’s actually because everytime you try to add a new email account you are lured by the Gmail symbol leading to the default configuration.
Even though firmware versions 1.1.3 and later configure IMAP by default and not POP, there are some features you still don’t get access to. Push email and offline messages are two most important features I see lacking. I travel a lot and Push email is a must have for me as I need to stay updated in realtime. I don’t remember ever manually checking email on my iPhone in the past two years. Full instructions to setup Gmail via Exchange after the break.
