Custom Status Bar in Apps Pages

Hey so Im looking for a customizing tweak that allows theming to the status bar,

I have a few themes that change the colour of it when on the springboard but not in actual apps or even the IOS settings menu, they are all stuck at the boring grey with blue icons, there must be a tweak in Cydia somewhere, googling this brings up long winded ways of making your own status bar but im unsure whether I want to go diging in my iphone files and whether or not they actually keep the theme change throughout EVERY window, springboard to settings to messages to safari etc
