This isn't true GPS then. This sounds like aGPS. When I put my Samsung Moment in Airplane mode, I cannot get a GPS fix. For starters, true GPS shouldn't have anything to do with Airplane mode, as it is a receiver only, and transmits nothing...just like a plain old FM radio (tiny, tiny reflections aside, of course). Secondly, when I'm not in A/P mode, but enter a dead zone, I again cannot get a GPS fix. I've tried the #GPSCLRX#MSLnumber fix, and this didn't change anything. When I called sprint to ask what was up, their "advanced" tech support said "of course; if you're in Airplane mode, how can it send a signal out?" This showed no understanding of GPS whatsover, but alas she was correct in effect. No cell network: no GPS. What's odd, is that even though I have disable "use networks" in the locations settings, I still DO get a (fast) fix if the phone radio is on and I have a signal. Anyone want to shed some light on this?
