If you're a Sprint customer who's anxiously counting down the days until you can get your hands on a shiny new iPhone 5, there's something you might want to know: Although the iPhone 5 has a lot to offer, Sprint's version of HD Voice won't work with the new phone. That's not to say you can't enjoy the shiny new phone and place clear calls on Sprint's network, but if you're uber-picky about clarity, just know you won't be able to use HD Voice.
Apple has advertised the iPhone 5 as supporting "wideband audio" which carriers often market as HD Voice. Sprint's spokesperson Michelle Leff Mermelstein recently told Phone Scoop that its version of HD Voice, which uses CDMA 1X Advanced technology, is incompatible with Apple's new phone. Other carriers use WCDMA networks to offer similar voice-quality enhancements.
We doubt this will be a deal-breaker to most customers, especially considering Sprint still offers a great unlimited data plan.
