Colorlines' Jamilah King has been on the Net Neutrality and mobile beats for a while. But her new piece really ties things together. Its title, "How Big Telecom Used Smartphones to Create a New Digital Divide," pretty much says it all.

Using fascinating graphics like the one pictured here (which use invaluable data from the Pew Research Center's Internet & American Life Project), King illustrates how "there are, in essence, two Internets emerging in the United States." There's the wired Internet, which has driven innovation and commerce for years and users have basic protections, and the wireless Internet, where "companies are free to do as they please with customers — they can control what users see, do and say online." People of color are disproportionately dependent on this second, closed Internet.

Those without access to affordable high-speed broadband in their homes must rely on mobile broadband on their phones. But since the FCC's Net Neutrality rules do not cover wireless devices, the wireless Internet is completely open to abuse from carriers like AT&T and Verizon. And as we see nearly every day, the carriers are all too willing to block our access to the open Internet.

The mobile carriers are controlling access to a tool that is essential for everything from political participation to employment to getting an education. Read King's piece to understand why it's so important for us to stand up and protect mobile users' rights.
