CustomSiriBG lets you change the Siri interface background

If you’re interested in changing the default background of the Siri interface to something new, then you just might want to check out a newly-released and free-to-download jailbreak tweak dubbed CustomSiriBG by iOS developer TylerD3V.

In the screenshot example above, you’ll notice that the default Siri background has been changed to something more Pokémon-centric, and of course, you can always use something different if Pokémon isn’t your thing.
