Of course, this is clearly a scam: the app, which imitates Ryan Petrich’s free Activator jailbreak package, does not grant that which it outlines in its release notes:
How to use multitouch gestures in iPhone/iPod touch
How to change the way of accessing IPhone/iPod touch
How to assume custom buttons or custom gestures for original buttons
In short, avoid this app! Because it’s an App Store scam. If you’re looking to customize your handset and create custom gestures for specific actions, jailbreak your iPhone and download Ryan Petrich’s (@rpetrich) free Activator package from the Cydia Store.
