So I just got this update, and surprise it still doesn't allow voice and data at the same time. So I chatted with a rep, and surprise this only works if your on an HD call with another HD compatible phone. Now either the rep has no idea what they are talking about which is not unusual for Verizon reps or Verizon deceived it's turbo customers, which I would not put past them as they have lied to me on several occasions.
A software update for the DROID Turbo by Motorola will be pushed out in phases starting today. The update enables Advanced Calling 1.0 so customers can enjoy HD Voice and Video Calling with other compatible Verizon smartphones. The update also enables simultaneous voice and data use so customers can talk and surf the web at the same time. Customers will be able to manually download and install the software update later today by going to Settings > System Updates > Check for System Updates.
To be honest, I could care less about this feature as I never found myself on a call and then doing something that required data, but the point is Verizon was never clear on this.
