I was under the impression you could use the GV app as a way to make calls without actually using your talk minutes, is this true? My g/f claims she knows people that are always using GV to make and receive phone calls without actually burning up any of their talk time minutes with their LG Optimus V smartphones on the Virgin Mobile plans. Is she out of her mind or is this really something that is possible? It seems like it can't be true and I've told her this, but if you could please help put this issue to rest, I would greatly appreciate it... thank you!
