If you’re an avid Twitter user and also happen to have a jailbroken iPhone or iPad, then you just might take a liking to a newly-released free jailbreak tweak called Crayola X by iOS developer aesthyrica.
Just as the name implies, Crayola X empowers you with the ability to give the official Twitter app a fresh coat of paint. The tweak adds an extensive preference pane to the Settings app where you can customize almost any element found in the app.
