LEADING THE DAY: Stopping the clock on a second AT&T deal, the Federal Communications Commission decided late Monday to combine its review of the company’s proposed dealings with T-Mobile and Qualcomm. In a letter issued by the Wireless Communications Bureau, the agency stopped the 180-day shot clock on a spectrum proposal between AT&T and Qualcomm, Politico reported.

Saying that the two deals raise several related issues, bureau chief Rick Kaplan wrote that the agency has “concluded that the best way to determine whether either or both of the proposed transactions serve the public interest is to consider them in a coordinated manner at this time, without prejudice to independent treatment at a later date.”

Sprint Nextel and other, smaller, carriers filed a motion to consolidate the proposals in late April.

In a statement, Dean Brenner, vice president of government affairs for Qualcomm, said that the deals should not be lumped together. “The FCC should approve the pending AT&T-Qualcomm spectrum sale now because of the clear benefits to the public from the sale that stand on their own and are totally unrelated to the proposed AT&T-T-Mobile merger.”

London riots: Twitter and BlackBerry Messenger have been identified as two of the tools that rioters in London have been using to coordinate their violent efforts, The Washington Post reported. According to the report, police have threatened to arrest those inciting violence over social networks.

David Lammy, the member of parliament who represents area hardest-hit by the riots, called on RIM on Tuesday to suspend the service.

Verizon strike continues: On the second day of a strike by about 45,000 Verizon workers, tensions rose as protestors accused managers of injuring three workers while driving past picket lines and the company accused workers of blocking entry into stores and cutting fiber-optic cables, the Associated Press reported.

Cary Sherman appointed RIAA CEO: Cary Sherman was named as the new chairman and chief executive of the Recording Industry Association of America Monday. He succeeds Mitch Bainwol, who will move on to become the CEO of the Alliance of Automobile Manufacturers.

Sherman has served as the organization’s president since 2001. No stranger to Washington, he was a partner and IP head at D.C. firm Arnold & Porter before heading to the RIAA to be its general counsel in 1997. He is also chairman of the board of the Levine School of Music.

The RIAA credits Sherman with coordinating the “copyright alerts” program, a joint effort between Internet service providers and the entertainment industry to stop the illegal downloading of copyrighted material.
