So the feature that I have used on 3 iPhones for the last few years will no longer work in 45 days time? My current iPhone will be the last device I am able to get push mail and contact syncing on? When my phone finally dies, and I get another one, I won't be able to have the same functionality I had today? How come the future has so many less features... This is a joke, right?
