General Settings
These settings control how frequently the information on the Weather widget is updated and the temperature unit to use.
Refresh interval Allows you to set how often to update (Manual, Every 1 hour, Every 3 hours, Every 6 hours, Every 12 hours, Daily) the weather. More frequent updates trade the convenience of current information for increased data use and decreased battery life between charges.
Temperature unit Allows you to set it to display degrees in Fahrenheit or Celsius.

Google Location Services must be checkmarked to update the
current weather. From the Home screen, touch Apps Key 
> Settings 
> Location
> Google Location Services.
