The developer, nin9tyfour, has been working on the tweak for a few weeks now and he's submitted it to the BigBoss repo. It'll be 99¢. This tweak looks really slick and more polished than Eclipse. He's even managed to get Calendar and Mail working, too. And now, the obligatory pics: App Store: Calendar: Music app: Settings for the tweak: You can customize the tint level with RGB sliders. There is also a Flipswitch toggle for activation in CC. Note: you have to kill apps you set Nightmode for.
