As i understand it
Sprint has really nothing to do with NORMAL Uconnect
You pair your own cell phone to Uconnect & use it as you Normally would for phone calls etc.
For $21 a month you can use the APPS that i don't believe exist yet ????
That may work with Sprint
here is something that i found online, but it was written last August & i believe is incorrect
this is possibly more accurate, but just as confusing
This is currently what is going on
