I am due for an upgrade to Iphone 4 which I'm planning on pre-ordering. My wife whom is on another carrier wants the new Iphone 4 as well so we're planning on converting her line over to my account. Question is, how can we pre-order on June 15th both phones? I've read from other forums that pre-orders are limited to one unit (the master unit) per household so is the only way to hope that when we pre-order one and pick up at the Apple / AT&T store that they'll have another one? I called Apple Customer Service and they directed me to contact AT&T which uh...no! Anyone have suggestions? Thanks.
