Now before you get too excited, this is just a workaround and it won’t actually fix the button, but if your iPhone is jailbroken, this is your best chance at getting control over this broken home button again…
All you need is a jailbroken iPhone and Activator, which can be downloaded from Cydia. Evan explains on his blog:
If your iPhone is jailbroken, install Activator from Cydia. Find its Settings, and make gestures or other buttons to emulate your broken buttons.
For me, I shook the device to return to the home screen and I swiped up from below to activate the application switcher.
So in short, you have to use Activator and set it up with a gesture to activate the Home function.
It’s very simple and I’m sure it will help lots of iPhone owners with flaky home buttons.
