*Adjusting your weather location
To change the weather go to http://www.weather.com and enter your location, then click on the "Find Weather" tab. Next, in the address bar, copy the 8-character code (Example: ITXX0042 = Milan,Italy). Open the LockBackground.html file and search for "var locale" then paste your weather code in the "ITXX0042". If you want to change the weather to Fahrenheit, search for "var isCelsius" and then change this to "false". Example: “var isCelsius = true” will display your temperature in Celsius.
