Stay far away from AT&T store. Generally untrained and disinterested staff. My experience on May 16, 2016 at the Northpoint mall store as follows. New sales person. Nice guy, but not yet ready to answer questions or set up phone. Phone was completely dead, several versions back level OS. He did not know to check before he attempted to move data. He said it would take 10 minutes to move data. After 2 hours, I took home a phone with 18% battery charge, no OS update, and no data moved. Their in store wifi showed 30 minutes to download OS, and never did. At least five different techs and "managers" strolled by to offer advice, which seemed to help nothing. Serious management quality issue. Manager did not give a damn about his job or the store. Mostly stood around talking to fellow employees, and did not care that his newbie sales person needed some help, even after several requests for help. I have purchased from this location before. Fool me twice, shame on me. Apple Store is crowded, but vastly more professional.
