I really need to remember to watch OP's video when I get home. This is very exciting. So to get data, you had to activate a Verizon device and swap SIMs, right? After that, the only thing not working is the CDMA voice? So in theory, if the above poser's link is correct (Verizon rolling out VoLTE soon) I could actually switch to them?
It's Verizon so I probably wouldn't do it permanently, but it would be cool to try for a month, if for nothing more than a proof of concept or neat trick. Hope Verizon does that soon.
