There are big reasons to care:

1. It sounds so much better. When you're talking to someone you care about, it makes a huge difference and you feel closer.

2. It is a huge improvement in noise canceling.

3. It can help protect your hearing (dispersing a sound over more frequencies rather than pumping up limited frequencies for volume) and reduce ear fatigue on long calls.

Once you experience it, you will care.

I'm sold, but phone conversations are two-way. How much benefit will I notice, or will my wife notice, if both phones are not HD?

My impression is that when talking to a landline, you should hear pretty big improvement, since the limitation there is the cell network's vocode, which is part of the HD voice improvement. Noise reduction should work from you to them and usually isn't a problem the other way around.

As for non-HD to HD phones, I think there's still some improvement, since the network's vocode is what strips much of the spectrum, but I'm not certain about that. Next time I'm in Germany I'll test it out.
 
I'd really like to know where you people with flawless AT&T coverage live.

I travel all over California, frequently, and have CRAP for service. I've used BlackBerry's, Androids, and every iPhone since the first one; I currently use an iPhone 5. I drop calls - multiple times a day. If I do have good coverage (4-5 bars), the bandwidth available to me on 4G or LTE is nothing short of awful a lot of the time: slow browsing, Facebook timeouts, etc.

I just returned from traveling in China and roaming on China Unicom (I believe it was anyway, I don't read Chinese). On China's 3G network, I had faster and more consistent data than I do on LTE on AT&T here in SoCal, and my voice calls were more clear, everywhere I went except one small city.

AT&T is an awful joke that I hope dies an awful death. We all know its just Cingular rebranded anyway; Cingular's reputation got SO bad, they had to take on AT&T's name.

I live in southern California and have none of these problems. LTE coverage is just as good and speeds are better than Verizon here in San Diego. I've yet to go to a location where I don't have LTE and my cousin with Verizon does. There has been a couple where I DID have LTE and he did not. To make matters worse, Verizon's fall back 3G network is WAAAAY slower than ATT. In most areas, we both have LTE coverage and he has yet to beat me in a speed test.

I live in Denver and spend a lot of time in Boulder where I had Verizon for 5 years. Now I've had AT&T for 5 years and it is about as good. Each is better in some areas than others, but overall good. I hardly ever drop calls and I'm constantly driving from client to client. I get killer LTE speeds in Denver too - I've clocked over 40Mbps.

I do know the pain of AT&T service in NY, Los Angeles, and San Francisco however. I have friends there whom I talk to daily and suffer their dropped calls left and right. But AT&T is great for a lot of other areas.
 
They can have my grandfathered unlimited when they take it from my cold dead hands. They take it, I'll jump to T-Mobile, and by the time that happens, there won't be a difference. So they best leave me the hell alone.

Grandfathered plans are already excluded from FaceTime. It would not surprise me if AT&T found new ways to try and pry it from "cold dead hands." (I qualify as well.)
 
We've had HD Voice on Three UK network since the iPhone 5 was released last year. It's great :cool:

Indeed. No point in having wider band if almost all your family and friend still use 2G, GSM voice transmission.

I wondered if the iPhone was able to gracefully switch to GSM band for voice when 3G or LTE are not reliable in a given area. I always felt that, to save battery, voice should go on 2G whenever possible.
