In a big win for companies like Skype, AT&T announced Tuesday that it has taken the steps necessary so that Apple can enable voice over Internet protocol (VoIP) applications on iPhone to run on AT&T's wireless network. Previously, VoIP applications on iPhone were enabled only for Wi-Fi connectivity but AT&T has offered a variety of other devices that allow VoIP applications on 3G, 2G and Wi-Fi networks. AT&T Mobility & Consumer Markets President Ralph de la Vega said the decision was made after evaluating customers' expectations and use of the iPhone compared to dozens of other products offered to subscribers.

Telecom analysts Rebecca Arbogast and David Kaut said the announcement was not only good for Skype but also for AT&T's "political and rhetorical position as the FCC attempts to write network neutrality rules, including for wireless broadband providers." The AT&T move is noteworthy, but not a surprise, in light of the AT&T August response to FCC questions about Apple's decision not to allow Google Voice to be carried on the iPhone through the App Store, the wrote. The announcement does not change Apple's position on Google Voice -- a situation the company said it was still "pondering."

FCC Chairman Julius Genachowski issued a statement late in the day commending AT&T for its action. "Opening wireless services to greater consumer choice will drive investment and innovation in the mobile marketplace," he said.
