Okay, I have a question. So, according to this thread, the Apple Store won't let you leave the store without activating your iPhone - but since I'm doing the upgrade swap -and I shouldn't used iTunes to activate my iPhone because it will kill my current sim, what should I tell the Apple Store? Will I be able to leave the store without activating my iPhone, so I can call or visit an AT&T an get the upgrade swap done? And the microSIM, does one come with the new iPhone? I only have the old one.
