T-Mobile restructuring: T-Mobile is restructuring and eliminating 900 jobs, the company said Wednesday, in order to “better respond to market and customer demands.”

Earlier this year, T-Mobile announced that it would be consolidating some of its call centers as part of a larger restructuring effort. The company did not specify how the company would be reorganized.

“With these changes, some jobs will be eliminated, some outsourced and some created,” the company said in a statement.

FCC eliminates duplicate Lifeline subscriptions: The Federal Communications Commission announced Wednesday that it has cut more than 135,000 duplicate Lifeline subscriptions. Ending the subscriptions, the agency said, has generated $15 million in savings.

Lightsquared: House Republicans on Tuesday criticized the FCC’s “sloppy process” in handling a waiver that allowed LightSquared permission to build its broadband network. The FCC has since reconsidered that decision, and LightSquared filed for bankruptcy on Monday.

In a statement, Reps. Fred Upton (R-Mich.), Greg Walden (R-Ore.) and Cliff Stearns (R-Fla.) said that their investigation into the FCC’s process was ongoing. “Now, more than ever, we need to get to the bottom of how we got this far down a dead-end road,”the lawmakers said. “There are many unanswered questions, specifically about whether the FCC’s own objectives led to sloppy process. We are continuing to examine the information we’ve received so far to determine what happened and how it can be avoided in the future.”  

Facebook GM ads: General Motors threw cold water on the buildup to Facebook’s red-hot initial public offering Tuesday, saying it will stop paid advertising on the social network, just days before Facebook’s market debut. The carmaker has found that its paid Facebook ads are not effective enough, a person familiar with the matter told The Washington Post.

Facebook declined to comment on GM’s media strategy, which was first reported by the Wall Street Journal.

The company added more shares to its initial public offering Wednesday and is expected to begin trading Friday.
