When iOS 4.3 was launched in its beta stage, a lot of buzz circulated regarding its multitouch gestures for returning to the home screen of iDevices and also to switch between the apps and how to activate it on iOS 4.3 beta. You need to install Apple’s Xcode in order to activate that functionality.
Now, those days are gone 🙂 I mean to say you need not to install Xcode now because a new teak is available on Cydia store that activates the Multi-Touch Gestures with just the tap of a button.
After jailbreaking your iDevices, download MT Gestures from ModMyi repo and activate it inside WinterBoard.
Close your fingers to go back to your device’s Homescreen.
By using 4 or 5 fingers, you can scroll up or down to hide/show Multitasking Tray.
To switch between apps, scroll to left or right (with four or five fingers).
Please note that this tweak does not work with iPad and it only works with iPod Touch 4G and iPhone 4.
