I hope this isn't too irrelivant to this forum... I just have a quick question. I tried using GPS with airplane mode on once, and to my surprise it worked. Does this mean that the GPS doesn't use data in airplane mode? It's all very confusing, because with data on, I can clearly see that the GPS drains my data when I use it. So how does it work in airplane mode then?? (i.e. even in airplane mode, it knows my location and gives me directions) Note that I was not using WiFi when I did this.
