I am holding out to likely get the 3G version later in the month. Here in the U.S, it will be exclusive to AT&T (which I have since my wife and I also have 3GS iPhones). My question is, when I get the 3G iPad, will it be added to my existing AT&T account? Or will it be a separate setup? If added to my existing account, I'm hoping that the data plan will get the same discount that my 3GS data plans get.
