Hm,I m fairly new to GPS technology. I ve downloaded some GPS test apps and the like and it works fine. Why cant I use it for navigation? My preinstalled WisePilot app has expired. Still it took it too long to find "service". Apart from that google maps needs Wifi or 3G internet all the time to function,right? So,thats it? No GPS without internet on the phone? Any alternatives to Wisepilot software? N.
