Here is a new tweak now available on Cydia. Basically the tweak allows an Android interface for multitasking on your iOS Devices.
It works fine in iPhone 4 and iPod Touch, requires iOS 4.0 or higher
All the recent apps you open, toggle like those on an Android OS. Android Recent Apps works with an Activator toggle settings, so you will have multiple options for toggling it. You can configure the activation method from Activator in Settings app.
Short Hold on the home button is recommended since it is the closest to the actual android method or you can change it to Double tap home button so instead of the iOS multitasking Android Style multitasking will appear.
Android Recent Apps displays up to 12 of your most recent apps and allows you to easily launch them even if they are already closed. So it’s not only multitasking but also shows the history of recently opened apps on your iPhone and iPod Touch. It does not allow to delete the apps running in the background though.
The tweak will cost you $ 149 and it is worth every penny. The cracked version is now available in the IHR (iHacks repo). It is available in BigBoss Repo, try it out and let us know what do you think about it.
Here are some screen shots for you.
