Now, this is really cool! The Time of Day theme available via Cydia changes the wallpaper image based on the time of day! This is a WinterBoard theme so, you will have to have WinterBoard installed before installing Time of Day. Once you have installed the theme, you can go into WinterBoard and select it from the list of files. Then, hit your Home Button and your iPhone or iPod Touch will respring and you will have the Time of Day theme. The theme does not change any icons, they remain as the stock icons but it automatically switches between five wallpapers based on the time of day! It determines the time of day based on the time set on your iPhone or iPod Touch.

In the wee morning hours, you get a nice sunrise wallpaper. A little later in the morning, the wallpaper will change to a daytime image. Toward late-morning/early-afternoon, it will switch to another daytime wallpaper with green grass and a blue sky. Later in the evening it will change to a wallpaper of a sunset. And during the night, you get a nice evening sky wallpaper.

Demonstrates one of the cool feature of WinterBoard!
