"Today's decision was made after evaluating our customers' expectations and use of the device compared to dozens of others we offer," said Ralph de la Vega, AT&T's Chief Executive.
AT&T, the exclusive U.S. carrier to the iPhone, said it had informed Apple and the Federal Communications Commission of its decision to allow Internet calling over its network, which was in response to a regulatory inquiry into the wireless industry.
The move allows Skype to file its voice application with Apple, which would then review it and decide whether to approve it for its iPhone.
Previously, AT&T only allowed Internet calling apps to use less reliable Wi-Fi connections, since services such as Skype and Google Voice bypass the standard telephone network by routing calls over the Internet -- allowing users to make call free of charge and to connect with landlines or mobile devices at low rates.
On October 22, the FCC is expected to propose new rules for net neutrality, requiring telecoms to open their networks to any legitimate Internet content or service without discrimination -- ensuring consumers can use the Internet as they please and without providers interfering with their competitors' services.
