I see where this question was asked and answered but I'd like to ask for an update. We were informed that there would be a software update for Advanced Calling 1.0 software update to enable Simultaneous Voice and Data some time in January of 2015. It's now the end of May and those of us with the Z3V are still waiting for this update. I was not informed of this phone's shortcomings with simultaneous voice and data usage when I upgraded in March, even after explaining my typical use of the phone. I'm now stuck with a phone that doesn't work for me as I need to sue it.
Can someone please provide me with an update as to when, or if, our Z3V's will be capable of voice and data usage simultaneously?
