Let’s be honest, the iOS task switcher that springs into action when you double-click the home button isn’t the most user-friendly implementation of task switching on mobile devices. Truth be told, many people who played with webOS devices came away impressed with the card metaphor efficiency, allowing you to quickly flip running tasks in and out of the screen. It feels right and quickly becomes second nature. You can now have that same card switching multitasking interface, on your jailbroken iPhone or iPod touch (iPad version is coming soon) by downloading the CardSwitcher tweak in the Cydia Store. It feels a lot like task switching in webOS and you can assign your own action to invoke it using the Activator tweak in the Settings app, as demonstrated in the above video.
