T-Mobile has been pushing their new HD Voice technology pretty hard lately. The new feature is said to produce much clearer audio during calls and eliminate the "tinny" sound most of us have become accustomed to.
Today, T-Mobile announced that the HD Voice feature would in fact be coming to its version of the iPhone 5. While HD Voice technology does exist in other parts of the world, T-Mobile will be the first carrier in the US to offer such a service. This also means that T-Mobile will be the first partner of Apple to put the iPhone's "wideband audio" capabilities to use.
To take advantage of the new clearer voice calls, all parties on the call must have a T-Mobile device and be connected to the carrier's HSPA, HSPA+, or LTE networks. The iPhone 5 is expected to launch on April 12 and will cost $100 up front with 24 monthly payments of $20 added to your bill each month.
