I have spoken to the iphone "experts" at Apple and they were of no assitance to this - Everytime I even view my contacts (from the phone or from the Contacts icon) all my email is downloaded to my phone. Normally this isn't a problem. But occasionally there are a lot of emails to be downloaded, and this causes a several second delay in my being able to make a phone call. This is annoying. When I want to make a call, I don't want to wait for my email to download.
I have Fetch New Data turned off. Oh, and just now when I was checking my settings, my email just downloaded by itself again...
Thanks ahead of time for your possible solutions.
