SBCoders has developed another awesome Cydia tweak called Aero. This tweak is an awesome new way to access your app switcher. You get a sleek new app switcher right on your screen allowing to open any recent opened apps. Aero has a few selections of different animations for your liking.You can purchase this app for $1.99 and I believe it is worth every penny.
Requirements: iOS 5 or greater
Description: Awesome new App switcher!
