I've had WeatherBug on my 8350i for about a week now and I have noticed that it only updates when I am connected to a WiFi connection. If I switch off the WiFi and let it try and update via the mobile network, it says it (Could not connect to WeatherBug) and will not update...even if left for hours!
I can not find a setting or find via the web if this app is a WiFi only application!
WeatherBug v 1.0.0.325
BB 8350i Boostberry
v4.6.1.204 (3.0.0.73)
I dont believe weather bug works but you may want to try BB Weather, it works perfectly fine, and updates on the desktop, and works with the native tcp
