I called Sam's this afternoon and no phones yet
So I called the closest ATT corporate store and they said they would, but that it would take some time to do a work around becuase of the taxes.
So I wen there and the first guy says NO.
Then the other customer services guy overheard this and said yes they do.
They told me this came about this morning that they would do 3rd party retailers. I'm thinkin' Samsung is trying to get them swapped ASAP because of liability concerns.
So I would recomend not giving up because the store says no at first. Ask to speak to the manager and challenge them a bit.
