So for the iPhone, if you have an AT&T business account, you can only purchase it through AT&T, whether that's online, over phone, or in store. You cannot purchase it through Apple, or any other outside retailers such as RadioShack, Bestbuy, etc. Is this the same with the iPad? Say I was to buy an LTE iPad mini and use it on that AT&T account. Do I have to buy it through AT&T or can I go through Apple?
