Why I'm using a Jailbreak on iOS

iOS is a great mobile OS because it (mostly) just works without much hassle: Simple setup, easy configuration and beautiful design. But there will always be something somebody won't like, for example I dislike the current design of the upcoming release iOS 7 because of it's gaudy colors and it seems I'm not the only one. But that's good, because there's always a way you can improve your experience and a Jailbreak enables tweaking the device even beyond the restrictions of the vendor.
