I've been reading some other posts, all about the GPS and A-GPS or Assisted GPS, which basically assists the GPS receiver in acquiring your position quicker. So if that's the case, then how could a position be off by miles? That makes me think that it's not GPS at all, but rather going off cell towers and wifi signals. And what if I'm in an area where I have no cell covereage period? Can I find my position? And a side question, I'm asking all this because I want to be able to find my lat/lon at any patricular place. So I'm curious... if it is a true GPS, then why is there no way (that I have found) to obtain your lat/lon from a native iPhone app? I thought maybe the compass would, but I don't see it, unless it has something to do with the location arrow on the bottom left that does not allow me to select it. And if there is not a way to obtain this via a native iPhone app, are there free ones out there which actuall work? The one I tried was GeoMarker, but that gave me lat/lon at least 3 miles away. A lot of questions I know, but any help is appreciated.
