Lately my 3G GPS has been really crappy! The app will open fast and pinpoint my location fast but it won't be where i really am. It is usually 2-5 miles off course. Could this do anything with a faulty chip or reception interference? Or could it have to do anything with software? It is really bugging me because i use maps a lot but not lately since this is always a problem, im on 3G not edge or gprs! Thanks!
