A buddy postulated that it might be possible to use an iPhone in Quetico (not for making calls/texts, obviously) but as a way to type trip notes (and make voice recordings/take audio) as we go along as well as use the camera and video functionality. He has a solar charger that can recharge the device pretty well he thinks (given that there's sunlight, which on some trips has been dicey!).

What I am wondering is can you use the GPS/mapping function on it? I know it won't be on a cellular network or anything, but I know apps like OnX hunt say that they work even when you don't have cell service. Does anyone know how this works? The device is small and light and if you put it in a LifeProof case, it might be able to be an asset.
