imsosick1216, Im in the same boat as you, Im a manager of an authorized dealer and we cant carry the iPhone. Now that doesn't mean they leave with no service.
I simply set up the account. Get them a free phone and tell them all they have to do is buy the iPhone take it home. Once they're in iTunes they can use the existing customer portion and Viola! They have an iPhone and I have a sale. And for all you corp. guys out there all you guys even do is just sell them the phone and let them be on there way. It's not like they leave the store with an activated phone!!! Unlike my customers, and they have a backup phone incase anything happens. But I wont sit here and bash on corp. cause we all work for the same thing and thats AT&T, Phones, and our paychecks!
