att.com/note7 has the information updated - it states you can return the new Note 7 for any Smartphone
Are the new Note7s safe?
Based upon recent customer reports and ongoing investigations by Samsung, AT&T is no longer exchanging customers into new Note7s at this time while we wait for the outcome of the investigations. Assuming the investigations complete successfully with no safety issues identified, our current plan is to resume exchanges with new Note7s at that time.
Is this a stop sell?
No, this is a stop exchange. We have not been selling Note7s since Samsung and the CPSC instructed us to stop selling Note7 devices purchased before September 15. The new Note7s that arrived in our stores on September 21 have been available for exchanges to customers with recalled Note7s.
Can customers with a new Note7 exchange it for a different smartphone?
Yes, customers can exchange their new Note7 device for any other Samsung smartphone or any other smartphone.
