At the AT&T media luncheon today, AT&T claimed that its popular smart phones, including the likes of the BlackBerry Curve and Palm Centro, would be replaced by 3G versions of the same handsets in the “coming months.” We learned this after someone in the crowd asked why other carriers, Verizon for example, have a high-speed Curve and AT&T doesn’t. The defensive response above followed, that all of AT&T’s smart phones would soon be 3G capable—including the long awaited 3G iPhone.
