While Senior Vice President of Worldwide Marketing Phil Schiller notably left out U.S. carriers when talking about the iPhone 5′s enhanced wideband audio at Apple’s event yesterday, we get clarification today from at least Sprint that the feature will not be supported. PhoneScoop reported that Sprint’s “HD Voice” service works on CDMA x1 technology, while the iPhone 5 and many other carriers around the world use WCDMA networks for the feature. Apple said the wideband audio feature would be available through 20 carriers at launch, but it only mentioned Deutsche Telekom and Orange.
