A Cydia package by the name of SiriToggles is out add some new features to your Jailbroken iPhone 4S. This package brings more functionality to Siri.
With the free SiriToggles tweak on your jailbroken iPhone 4S, you can launch any app, change your system settings, and even turn your iPhone off with your voice.
Apple may have restricted Siri to a limited set of capabilities by default. However SiriToggles liberates the virtual assistant for jailbreakers.
Not only can you launch an app with your voice (“Open Maps,” for example), toggling your iPhone’s settings quickly with Siri will also be possible. The developer, Hamza Sood, has included multiple system toggles that the average user accesses daily. With SiriToggles, you can toggle your iPhone’s Bluetooth, WiFi, Airplane Mode, and Data settings with your voice. All you need to do is to just say either “enable/disable” or “turn on/turn off” followed by the setting and let SiriToggles take it from here.
You can get your iPhone’s battery percentage by saying something like “How much battery do I have left?” or “What is my remaining battery percentage?” or “What’s my current battery level?” Your screen’s brightness can even be changed with Siri by saying “set/change backlight/brightness to x%”.
Using SiriToggles for more than a day, does not the battery life or performance of your iPhone 4S. This tweak is a great addition for any jailbroken iPhone 4S.
