In January , T-Mobile announced HD Voice was available on a handful of phones including the Samsung Galaxy S III and HTC One S. The carrier also said last month it will have HD Voice on the iPhone 5, to be rolled out on T-Mobile's networks in the U.S. for the first time later this month.
We're most interested in the ATIV S: thanks in part to Windows Phone 8's multi-core support, it's effectively a Galaxy S III for the Microsoft crowd with a similar 4.8-inch Super AMOLED HD screen, a dual-core 1.5GHz processor, a 8-megapixel rear camera and a 1.9-megapixel front shooter.
