I am using MobileMe with PUSH set ON & Fetch set OFF on the iPhone 3G yet about 9 out of 10 times mail doesnt get PUSHED to the phone UNLESS I click on the MAIL ICON. Once I am in the MAIL APP emails start coming in. I have deleted and reinstalled the MobileMe account 6 times already yet still MOST of the time I am not receiving email unless I actually go into the MAIL APP. The mail is on the MobileMe WEB APP immediately when I look on my PC but getting it pushed to the iPhone is the problem. Every once in a while it works.
