We’ve seen some other Siri jailbreak tweaks, but AssistantExtensions is probably the coolest so far. AssistantExtensions lets you launch apps, send tweets, enable/disable Settings toggles like Bluetooth, WiFi, etc., control brightness, respiring Springboard, search YouTube and more. And even more commands will be added in the future.
AssistantExtensions requires a jailbroken iPhone 4S and is available in Cydia for free.
Another feature of AssistantExtensions is the ability to have a conversation with Siri, check out the video below for a demonstration.
