Multi-touch gestures on the iPhone 4 with iOS 5.0.1

[biometrics]

My home button is stuffed. I've jailbroken it using redsn0w. The multi-touch gestures option is enabled in setting but apparently that only works on the iPad. There's a paid for app in Cydia and also the option of Activator.

How have you enabled it and how?

I'm mostly interested in the four fingers up (or similar) for the task menu and five fingers to return to the springboard.
