Hey, I understand if you have an AT&T premier account, you have to buy the iPhone from an AT&T store, to avoid any premier discount issues. I was wondering if I can buy it from Apple, if I have 4 lines on my AT&T account, with another number/phone listed as the primary premier account number? The iPhone number is not the primary account line and I would rather buy it directly from an Apple store than an AT&T store. Any thoughts? Thanks
