This is the HTC Hero Widget based on iVillain by Justflikwalk and customized by eCAR.
It doesn't change any icon or dock background, it just add the Widget on your LockScreen (not on the Springboard...).
By default, it take the background of "User Wallpaper" in WinterBoard but you can change it with a personal wallpaper by tuning "customWallpaper" in widgetSettings.js and "persoWallpaper.png" in "Widget" folder
You can change your location in widgetSettings.js as well as weather description language, temperature and hours kind (Fahrenheit/Celsius, 12H/24H), etc.
Unzip and place "Android Widget by eCAR.theme" folder in /private/var/stash/Themes.XXXXXX/ by SSH
/!\ use LOCKSCREEN CLOCK HIDE (source cydia : [link]) to hide the original clock on the LockScreen
