I pre-ordered a phone a few days after it all started and have an 3-4 week delivery date on my upgrade. What happens if I get in line at a store and get one tomorrow? Will they check the upgrade status and see it's been used with the online preorder? Or will they check the upgrade status and see it's OK because the phone ordered online has not been shipped yet? Or will they make me cancel the online preorder while in the store which then will release the upgrade? Or will I cancel the preorder and still not have the upgrade in the store because ATT systems won't update fast enough? Does anyone understand this question?
