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.

AT&T presents a flat rate $99 plan that includes unlimited voice minutes and data for all smart phones, together with the iPhone. However, unlike Sprint’s Simply Everything plan, the package does not include texting. Feature phone customers have the alternative of a $69.99 unlimited talk plan, while users with QWERTY smartphones can subscribe to an unlimited talk and text plan for $89.99

AT&T will be providing more or less $50,000 to Télécoms Sans Frontières (TSF), a humanitarian organization that specializes in emergency telecommunication systems. TSF send off an emergency reaction team from the American base in Managua, Nicaragua and plans to launch out additional support. Its employees are besieging road obstacles on the ground, but are hauling mobile and fixed telecommunications tools, as mentioned in the group’s website.

AT&T filed a request with the Federal Communications Commission (FCC) to replace its aging PSTN landline network with a broadband VoIP one. The company argued that since 99 percent of Americans have wireless coverage today and that 86 percent subscribe, most people no longer see the need for a landline phone, with 700,000 landline subscriptions ending every month. AT&T did not ask for a specific switch date, but under AT&T’s proposal the federal government would regulate high-speed broadband access.

New Yorkers observed that they weren’t able to obtain the iPhone from AT&T’s website last weekend, but as of today the phone is now available online. AT&T isn’t the only carrier under pressure with the amplified demands that smartphone owners are putting on wireless networks. Yesterday the Financial Times reported that O2, which also carries Apple’s iPhone, expressed regret to London smartphone owners after subscribers began complaining about the incapability to place phone calls occasionally during the second half of the year.
