Verizon is expected to launch the much anticipated HTC Thunderbolt 4G LTE phone in the coming weeks. Although there were some previous leaks indicating that the device might be capable of simultaneous voice and data, we were skeptical. CDMA networks running on EV-DO like Verizon have not traditionally been capable of this feat. But now Engadget is reporting that a new leaked document seems to confirm the Thunderbolt will have what is called SVDO (a modification of EV-DO). This would allow users to use voice and data at the same time on 3G.
