AT&T has stepped up its efforts to rebrand Cingular as AT&T Wireless in anticipation of the upcoming iPhone launch. “The iPhone is one of the most anticipated handsets ever in the wireless industry, and we want to make sure that every drop of equity from the iPhone accrues to the AT&T brand,” AT&T spokesman Michael Coe said in this Reuters article. AT&T will replace the interiors of its 1,800 shops on Monday but leave the outside the same. The tagline of its advertising campaign is: “Your world is wireless. AT&T is wireless.”
