AT&T customers, listen up. You can now use the HD voice feature of the iPhone 4S and iPhone 5; assuming you have one, of course. Recently AT&T announced plans to enable HD voice (also known as wideband audio) in an upcoming carrier update. Well, if you are too impatient to wait (like I would be), then you can install a hacked carrier update right now to use HD voice right now, and also the new Amber Alert feature to be rolled out later this year. That’s right, iTweakiOS, the same people behind the other hacked carrier updates, has released this carrier update, and you can install it right now.
This hack fixes the reported issue of unstable HSPA+ speeds/signal and iPad users having trouble updating and losing all signal. This hack enables, along with the previous enabled features, HD Voice for all iPhone models running on AT&T so users can now use the UMTS/HSPA/HSPA+ network for HD quality calling on their 4S and 5. This hack also enables Release 7 HSDPA speeds for the iPhone 4S, giving it a new maximum theoretical downlink of 21Mbps, which AT&T does indeed support. Signal improvements from the previous release have not changed and are still present in this release along with unthrottled LTE and HSPA+.
Whether or not this actually works for you, however, will depend on your location, simply because not all the AT&T network supports it quite yet. T-Mobile is currently the only carrier of the big 4 in the US to fully support wideband audio via the iPhone 5, and has supported it since its launch, not only since the iPhone 5 became available on its network. If you are interested, head on over here to check it out: iTweakiOS. Being on Verizon, this doesn’t do much for me, but hopefully Big Red will announce HD Voice at some point.
What do you think? Are you going to try this out? Let us know in the comments if it works, or tweet results to me @TiP_Kyle.
