There’s a new hacked carrier update available for iPhones running on AT&T, which delivers HD Voice, support for Release 7 HSDPA speeds on the iPhone 4S, and a number of other improvements. As always, you don’t even need a jailbroken iPhone to install it.
HD Voice offers higher voice quality for networks and devices, like the iPhone 5, that can support it. T-mobile has already announced its own plans to deploy the technology when it begins selling iPhone 5s later in the month. Sprint also has plans for the higher resolution mobile audio.
AT&T today announced its own support for HD Voice, with senior VP Kris Rinne telling group of technologists at the VentureBeat Mobile Summit that AT&T plans to roll out HD Voice support later this year, at the same time it starts running voice calling on its own LTE network.
For a brief moment during yesterday’s keynote, Apple mentioned that along with some new LTE and battery wizardry, they were able to add support for “wideband audio” phone calls. Some tech people are calling it HD Voice, because it’s really just higher quality voicecalls.
