AT&T Mobility has changed its stance, and is now going to allow VoIP applications for Apple's iPhone to run over its 3G network. The carrier said that it had informed both Apple and the FCC of its decision.

The change in policy means that users of VoIP applications on the iPhone, such as Skype, will no longer be relegated to using the device's WiFi connection for VoIP calling. It is also a significant turnaround for AT&T, which said earlier this year that allowing VoIP apps on the iPhone to run over its 3G network could cripple the network. Indeed, AT&T has openly discussed the strain iPhone usage in general has placed on its network.
