GPS sometimes works. But, why?
When I am in the area around the Shibuya or Shinjuku train stations, for example, I can use the Map app on my AT&T iPhone 3G with the SoftBank 3G SIM and pinpoint where I am. As I walk around, the usual blue dot follows me as well. But, this does not happen always. Often, as I try to find where I am in the Map app, it would say that it cannot connect to the internet.
When I do have GPS working, I cannot use Mail app or Safari app.
To be certain, I checked my iPhone and Wi-Fi was disabled.
So, the data part of the SIM was not working on my iPhone then. Yet, I had GPS.
This phenomenon of GPS capability here and there without data support is puzzling me.
But, May 23 is my last day in Tokyo this time and I will fly out of Narita on May 24. So, I will probably not be able to solve this GPS mystery.
Overall, my 2-week stay in Tokyo has been good with SoftBank's 3G SIM in my AT&T iPhone 3G.
I am sure that a whole new game will begin when Apple introduces a new iPhone in June.
