DOJ acting antitrust head to step down: Joseph Wayland, who has been the acting head of the Department of Justice’s antitrust division, will be stepping down from his position.

Justice spokeswoman Gina Talamona confirmed that Wayland’s last day in the department will be Nov. 16. His replacement has not been announced.

Wayland was appointed as the acting head of the DOJ’s antitrust division in April, replacing Sharis Pozen. The position has been filled by acting assistant attorney generals since the middle of 2011, when Christine Varney stepped down. William Baer, an attorney with Arnold & Porter, has been nominated to take her place but has yet to confirmed by Congress.

Wayland led the litigation team that challenged the ultimately failed merger between AT&T and T-Mobile. Under his leadership, the division also has imposed conditions on a spectrum deal between Verizon and cable companies and considered the issue of the use of standard-essential patents in intellectual property disputes. He also led the litigation team that won a case to block a merger between H&R Block and Tax Act.

AT&T expanding access to FaceTime: AT&T said in a company blog post Thursday that it will expand access to Apple’s FaceTime video conferencing application to all LTE customers, not just those on its Mobile Shared Plans.

AT&T had faced criticism from consumer advocates who believed the carrier’s policies were violating net neutrality principles by limiting access to the app. AT&T had defended its decision, saying that those guidelines were related to allowing consumers to download apps and did not apply to pre-loaded applications.

In the post, AT&T’s Jim Cicconi, the senior executive vice president for external and legislative affairs, said that the company limited access to assess the impact the app might have had on the company’s networks.

“We will continue to gather and assess the network data on this issue over the next few months and anticipate that we will be able to expand the availability of FaceTime to our customers on other billing plans in the near future,” he said.
