Verizon to Support Simultaneous Voice and Data Transmission?

We have been told that when the mythical Verizon iPhone materializes, assuming it's not a LTE unit, it might launch with VoRA; Voice over Rev. A. According to our source, Verizon has been testing VoRA as a precursor to VoLTE, and as long as the network upgrade timeline and iPhone release are aligned, we should see this happen.
Implementations of the CDMA2000 standard currently used by many carriers around the world, including Verizon, do not support simultaneous voice and data, a drawback viewed by many as significant in comparison to the UMTS standard employed by AT&T and all other current iPhone carriers.
