Well it didn’t take long for Siri tweaks to surface after the Untethered Jailbreak for A5 devices (iPhone 4S and iPad 2) went live several days ago. VoiceUtils, a newly released Cydia app developed by Nick Frey, finally allows Siri to open stock and third party apps, unlock the device, reboot/restart/respring the phone, and even enter Safe Mode. These actions were previously not available to Siri, and many users have wondered why Apple has decided not to (for the time being at least) include basic functionality such as launching apps. At least now for iPhone 4S jailbreakers, the free Cydia utility will give them more control over their device and simple actions like restarting the SpringBoard is only a voice command away. Check out the video demo of VoiceUtils in action after this space.
