iPhone 5 Won't Support Sprint's HD Voice At Launch

Apple's new iPhone 5 won't work with Sprint's new HD Voice service at launch, even though Apple touts the device as supporting "wideband audio", commonly marketed as HD Voice by many carriers. Apple claims that 20 carriers around the world will support the feature when the iPhone 5 launches. But Sprint spokesperson Michelle Leff Mermelstein confirmed to Phone Scoop that "at this time, iPhone 5 is not HD voice capable." The statement leaves open the possibility that an update will add the feature. (Sprint clarified its statement, after initially saying "it is not supported.") Most carriers offering HD Voice around the world are doing so on WCDMA networks, whereas Sprint's HD Voice service operates over CDMA 1x Advanced technology.

does any one know

So I can't seem to get answer to this question. Does the iPhone 5 not support sprint's HD voice because it doesn't have the proper codec or is it a hardware limitation. I know the modem the iPhone is using is Qualcomm's mdm 9615m but don't know if it supports CDMA 1Ã—advanced.

None, unless one of them announces something new.
