AT&T and Sling Media announced that Sling Media’s SlingPlayer Mobile application will now run on AT&T’s 3G network. AT&T noted that it will start running with other content providers to open up its 3G network. “Just as we’ve worked with Sling Media in this instance, we look forward to collaborating with other developers so that mobile customers can access a wider, more bandwidth-sensitive, and powerful range of applications in the future,” Ralph de la Vega, CEO and president of AT&T Mobility and Consumer Markets said.
