Apple added a nifty new feature to iOS 6 that adds a splash of color to the status bar. Rather than being just black or silver, the status bar now changes to match the color scheme of the app you’re running. In Skype, for example, it goes bright blue, while in the eBay app it goes grey.
I’m a big fan of this feature, but I know a lot of users don’t. With that said, if you’d like to kill it, you’ll be delighted to hear there’s a new tweak for jailbroken devices that does just that.
