Earlier today I’ve told you about the free tweak released today for jailbroken iPhone 4S called SiriToggles that will let you toggle Wi-Fi, 3G, launch Safari and a lot more, simply using Siri. Great tweak that you should definitely get.

Once you have that one installed, you may want to look at another cool Cydia tweak called Hands-Free Control. What’s so cool about this one? You can launch Siri without even having to hold down the Home button. Simply set a keyword that once you pronounce it, it will prompt Siri.

Thanks to this tweak, your voice assistant can be activated via a voice command, which is very handy to have when your hands are not free or you cannot reach the phone. Imagine you are in a hostage situation with your arms tied behind your back: you can tell Siri to call 911!! Just messing around with you!

As usual, to download this tweak onto your iPhone 4S, search for Hands-Free Control from Cydia and install it. The app is $2.99.

If you still haven’t jailbroken your iPhone 4S, here we have a tutorial…but I’m still suggesting, as I’ve done these last few days since Absinthe was released, to wait a few more days until the tool is debugged.
