Which way should it be.
If I get a new email that shows up both in Mail app on the desktop and on the Me.com web interface, on my iPhone it should:
a.) push almost immediately, whether WiFi or EDGE (don't have 3G) and my Mail icon on the iPhone home screen should update to the current # of unread emails in the red circle without having to go into mail. This is what I thought it should be, so you know without going into mail.
b.) it supposedly pushes, but you don't know until you go into the mail app inbox and it then shows the current emails, read and unread. To me, this seems like "pull" since that was how it was before. You had to wait until it connected and checked new mail. To me this defeats the purpose, as I want to know on my home screen when I wake my iPhone and not later. Or as someone mentioned, is this the September notification thing, where right now you have to go into mail, but in September, it will show up on the home screen.
BTW, my contacts and calendar are syncing/pushing fairly quickly and consistently between my iPhone, Me.com and my iMac desktop apps.
