A new jailbreak tweak makes use of the iPhone 5S’ Touch ID sensor. Rather than having to press it down to use it as a Home Button, you can simply touch it. This will simulate a press.
It works pretty much like the standard Home Button. Touch it to return to the Home Screen, etc. According to CultofMac, there are a few replacement functions. For instance, rather than a double-tap for the app switcher, you touch and hold.
It also says that it can’t yet replicate all the commands. For instance, Siri.
Oh well, at least it’s free and worth a shot.
