I can't figure out why my 32GB 3GS is behaving this way.
I use the "Maps" app that came with it, and it seems to work pretty well when Ihave both WiFi and Cellular Network Data turned on. I also use Trimble Outdoors Navigation, it also seems to work fiarly well. At least it can find where I am, within a few hundred yards. Not the accuracy I usually get with my old Garmin Emap, but at least it's something.
But when I turn off WiFi (using "Settings/General"), suddenly the 3GS hasn't a clue where it is, whether you're running the "Maps" app or the Trimble app. With WiFi on, it usually takes a few minutes to figure out where it is, but then it comes through fine. Not so when WiFi is off - I can stand in one spot for 10 minutes or more in a clear outdoor area, with either app, and it keeps showing where I was early in the morning, 12 miles away. Obviously it isn't getting a GPS fix.
Anybody know why it seems to lose its way when ***WiFi*** is turned off? I would have thought the GPS chip doesn't need WiFi's help.
A 3GS *does* have a GPS chip, doesn't it?
