But Sprint spokesperson Michelle Leff Mermelstein confirmed to Phone Scoop that the iPhone 5 will not support Sprint’s version of HD Voice. 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.

For those of you not on Sprint, you may wonder why the other 3 are not. For Verizon, it looks to be the same, however it is unconfirmed. AT&T and T-Mobile however should have no excuse, as they have the technology readily available for use. However, they are simply choosing not to put it in action. Here is a short explanation from Cult of Mac:

You can use a codec called AMR-WB over a 3G GSM networks like AT&T and T-Mobile, but they’re so busy rolling out their 4G networks that they won’t support it.

So it would seem they are just too preoccupied. If I wasn’t on Verizon and instead were on AT&T/T-Mobile, I would be upset about that. They have it but are just going to overlook it? I may be in the minority though with caring about it.

What do you think? Disappointed this won’t come to the US? Are you preordering the iPhone 5? Let us know in the comments.
