AT&T on Friday said it has successfully closed its buyout out Wayport. The deal hands over control of Wayport's Wi-Fi hotspots and gives AT&T about 20,000 access points within the US and a total of 80,000 worldwide. No mention has been made as to if and when Wayport will switch to using AT&T's official Wi-Fi system and how soon users of either service will have a common billing system.
