ATT wont sell them outright i tried that.
You can buy it out right from att, but it has to be activate through them or whatever they call it. Which is a big fat lie since any ATT device can accept Att sim right out of the box.
Some store insist you to buy a plan with the phone is also against the company policy but when you complain CS will just direct you to another store without taking seriously. Well obviously thats the only way to keep their retail store or partners alive I guess.
