Just in time for the holiday festivities, iOS developer Tristan Kennedy has created a snowy HTML widget for your jailbroken iPhone's home screen called SnowScreen. Simply apply the widget and you'll have a falling snow animation layered over whatever wallpaper you already have.
Without further adieu, let's show you how to apply this tweak.
As mentioned above, you will firstly need to jailbreak your device, if it's not already. Next, enter Cydia and select the "Sources" tab, tap "Edit," then "Add," and finally, enter "cydia.taskinoz.com" as the source.
With the source now added, you will be able to find the SnowScreen tweak through the search option in Cydia. Install it.
Now you'll need to install SBHTML, a tweak that'll allow you to apply falling snow to your home screen.
Enter your Settings application and scroll down to the "GroovyBoard" (aka SBHTML) preferences. From here you'll enable the tweak and select SnowScreen as the theme.
When you select SnowScreen, you will have a couple of clock options as well as the ability to adjust the amount of snow "particles" showing—the more you apply, the slower they fall, so test out different values. Once your changes are saved, make sure to reboot or respring your iPhone to apply them.
When your device is back up, you should have some beautiful snow falling over your wallpaper. Now all you have to do is find a winter wallpaper that'll bring the theme together.
