I wound up with another ATT phone because Best Buy couldn't let me know the night before if I would be able to purchase in store the next morning and my order on Best Buy's website said pickup the 15th so I drove to my normal ATT store where I bought most of my previous phones in which opens an hour earlier than Best Buy and they had the S10 model I wanted available for purchase and didn't want to take a chance since there was already two other people waiting at the door with me for the S10 so I took it.
ATT said on my pre paid plan that after 6 months of service that they'll unlock it for me and that it's done on their website and that I won't even have to call. Fair enough to me, I took the ATT phone to make sure I got one today and didn't have to wait until the 15th. And the person who asked, no ATT branding on the phone what so ever. Happy with the device so far and the packed in AKG ear buds are the best sounding buds I've ever used, even better than my Sennheiser Momentums (and the AKG's are the most comfortable too!) Major leap over past ear buds (remember how bad the S7's where? Yikes!)
