Free Press, Public Knowledge and the New America Foundation's Open Technology Institute have notified AT&T of their intent to file a formal complaint against the company asserting that AT&T is violating net neutrality by blocking video-conferencing application FaceTime. The groups will file the complaint with the Federal Communications Commission in the coming weeks. Under the agency's Open Internet rules, which prohibit companies from blocking such applications on their mobile networks, anyone filing a formal complaint must give at least ten days' notice of their intent to file. The complaint comes as Apple releases its latest operating system, iOS 6, which enables customers to use FaceTime over mobile networks. FaceTime use was previously limited to Wi-Fi connections. AT&T has indicated that it will block customers from using FaceTime via mobile devices unless they subscribe to one of its new Mobile Share plans. Under the Open Internet rules the FCC passed in 2010, AT&T cannot block apps that compete with the company's traditional voice-calling service.
