I am currently in Okinawa, Japan on a business trip. When I got here, I took my sim card out of my iPhone so I didn't have to keep the phone in Airplane Mode the whole time. I did this mainly so I could turn on the GPS radio. GPS had no problem finding me in the airport in Tokyo, but ever since then it can't find me properly. I brought my Airport Express from home in Tampa to my hotel here and when I tell Google Maps to find me with Location Services on, it places me at my home in Tampa. However, when I am away from the hotel on a different wifi network, even outside, it always comes up saying "Your Location Cannot Be Determined". Does anyone know a fix for this? I realize that its "assisted" GPS, but thats really sad if it confused Okinawa, Japan for Tampa, FL because of a router. And why won't it find me out in about on other wifi networks. Makes now sense.
