Regarding HD Voice and Carrier Hacked Update a few months ago

[iMore Question]

I recently switched to AT&T after being a longtime unlmited data power user on Verizon. I was wondering, if anyone knew if the iphone 5 carrier hacked update would work on the iphone 5s. I am wanting to enable HD Voice and open up unthrottled LTE for better speeds? Any help would be great thank you!

AT&T's network in your locale would have to support the functionality the 'hack' is supposed to provide... so, if the 'hack' worked on a 5S or not - being able to make use of the supposed benefits would depend entirely on AT&T's network where you are according to everything I've been able to find about it.
