I just came across this new tweak on Cydia. Haven't seen anyone saying anything about it yet but it's great. Siritoggles let's Siri launch apps for you as well as do other cool things such as turn off/on wifi, airplane mode, adjust screen brightness, ask how much battery life is left and much more. I have been using it for a bit now and I must say that it works great. Let me know why you think!
