Requires iOS 4.3 or higher
Multitasktures lets you switch between apps in the switcher by Activator-Gestures.
This tweak utilizes Apple's app-switching which was enabled in the betas for iOS 4.3, but was then disabled for release. Multitasktures lets you assign these Methods to Activator. Now you can switch between apps (for example) by swiping the statusbar left-right or by pressing the volume buttons.
Check out this developer's other apps:
AdBlocker
Firewall iP
FullScreen for Safari
FullScreen for iPad
ScreenDimmer
Multitasktures has no Settings. Go to Activator's Preferences and assign gestures. Only then you'll be able to use this tweak.
There are no new icons added to your homescreen, and no options to configure. This adds new actions to Activator, which you can find in Settings app.
