This app is great (version 3.1).
I made some tests with friends in different countries.
We found some errors on the location. My friend is in the same district than me, and the app says that he is in China.
In fact he uses his iphone with chinese language (version Taiwan). And JRealtime says that this IP is from Taiwan.
The geo location more is on IP address. The IP address I got, and search this from www.iplocation.net
. This gives me the correct location.
So, How to update the location database?
