Hello,
we have SE W800i for our tests and it works fine.
I have few ideas and few questions concerning your problem:
1. Did you connect GPS by Bluetooth before you choose FoxyTag screen?
You should have a screen with GPS datas like number of satelites quality etc..
Tip: go to "GPS->Search" and than connect your external GPS by Bluetooth.
Only after Bluetooth connection with GPS you can connect FoxyTag on Internet.
2. If after that you don't have Internet connection with FoxyTag try to use FoxyTest. If final response is "Your parameters are not well configured" try to configure Internet for java applications.
3. To configure Internet for java application go to Parameters->Connection->Parameters For Java
Choose profile that you use to connect to Internet with your Web Browser.
Hope it will help if not we allawas have ideas
but the time is a little problem
