Re: The hard part is the back end infrastructure ties...
I suspect that they could actually just have both running at the same time, as traditional voice and data are on CDMA only, and PTT are on iDEN only. If this allowed for PTT to handoff between iDEN PTT and QCHAT as well as standard voice and data to handoff between iDEN and CDMA 1x/EVDO, then I'd say they have it partially done. -- Canada = Hollywood North
