While apps only get better and better, giving us new and more interesting ways to keep in touch with each other, one component of the smartphone experience has seriously been stagnating: voice calls. That’s largely been due to voice existing separately from other phone data, and the system not being optimized for today’s high-speed networks and more capable devices. There are a few ways coming to help modernize voice, like VoLTE and HD Voice. The latter is something we’ve heard AT&T talk about implementing sometime this year, and the carrier has singled-out the iPhone 5 as an early device that will be able to take advantage of the increased call quality. Well, AT&T has yet to go official with its HD Voice offering, but a little iPhone hack can get you started with it early.
Supposedly, this release will enabled HD Voice for both the iPhone 5 and the iPhone 4S on AT&T’s network. Additionally, it includes some tweaked data settings that may offer higher speeds, although we’ve heard claims about changes like that refuted in the past.
There’s also the note that AT&T doesn’t yet support the HD Voice codec everywhere (unsurprisingly, for something still in development), so even with this hack, it may not make your calls sound any better just yet. If you’re curious, at least, hit up the source link and start reading through the installation guide.
