You must be insane to install a jailbroken software on a device that holds so much information about you and you rely on even for work. You can't get official security updates from Apple and the "hack" software does not come with guarantees from anonymous people let alone who knows what is going in the background of those apps or what it is doing to your iphone. This can be used on a spare iphone that you don't really care about.
That being said, there is some cool things in the video below, I won't say I like it but something are implemented better than Apple and looks better. How are they even able to do this stuff? Did they get the iOS source code?
I know Asus tends to give out the software to some programming enthusiasts and use them as beta testers and wait for them to invent new "features". There is jailbroken firmware for Asus routers called Merlin, thats how it works, or at least how I understand it works.
