Today, AT&T opened up its 10,000 square foot flagship retail store on Michigan Ave. in Chicago. It’s a bit of a beast, with an 18-foot Connect Wall that displays news and product info to everyone in the store and in the street.But despite all the cool technology (and trust me, there’s plenty), AT&T is really looking to have more of connection with its consumers. When you walk into any carrier store, the phone usually comes first. Samsung, Apple, and Motorola come to mind — not AT&T. But the blue carrier is looking to remedy that.
