I have an iPhone 3gs and when I go to my google maps app it tells me I am at a wrong address it tells me I'm about 8 miles away from where I really am how would I fix this issue? I've reset all the settings network and what not and also my iPhone to factory settings. It used to tell me just about a week ago that I was where I actually was but now it tells me I'm about 8 miles away giving the wrong my location. Thanks for the help btw I live in Tucson az
