I'm looking to ditch my old broken screen gps I use for hunting. I found an app I really like the motion x. Let's you save maps for offline also but here lies the problem. The iPhone GPS will NOT work when in airplane mode. (like the droid can) I'm looking to use this in the woods where I get low signals sometimes and do not want to kill my battery searching for a signal. Does anyone know of an app that would jut turn off the network cell signal without being in airplane mode? The AT&T phone is easy because u could jut pull the sim card.
