Users of Skype and other VoIP apps will be able to make calls on AT&T’s 3G network, reversing a previous decision by the company.
AT&T (NYSE: T) on Tuesday opened its 3G network to VoIP calls on the iPhone, reversing its previous position, as federal regulators consider applying proposed net neutrality rules to mobile phones.
AT&T’s decision applies only to Apple’s smartphone. The wireless carrier does not allow the use of voice over Internet protocol, or VoIP, over its 3G network on other mobile phones. Before the reversal, VoIP applications from Skype and other companies could make calls on the iPhone only over a Wi-Fi connection.
AT&T said it notified Apple and the Federal Communications Commission of its decision Tuesday. “Today’s decision was make after evaluating our customers’ expectations and use of the device compared to dozens of others we offer,” Ralph de la Vega, president and chief executive of AT&T mobility and consumer markets, said in a statement.


I have seen it time and time again. A small business with multiple phone lines, wants to save money by switching over to VoIP.
