@jimski - Yes I have seen it connect. I wouldn't call it seamless. I was browsing on my phone and it failed to load a page. I checked my connections and saw the wifi icon blinking. It then connected to i believe an "attwifi". I turned off my wifi and everything still worked.
@Rico - Yes. I have tried to look up the security aspects of wispr and haven't found much. I can tell it authenticates, but I can't tell if the connection is required to be encrypted. As such, I'd rather not connect to an AP I didn't ask it to connect to. Maybe there is a way to disable it thru the diagnostics app on Focus.
