Habe gerade etwas nettes gefunden bei Xda Deverloper
There are plenty of task managers out there for Android. Also, there are a lot of people who say that the multitasking abilities of OS 4 for the iPhone will be great once released. If you are tired of hearing arguments going back and forth about this, you may want to take a look at what XDA member agafi has made for you. Marrying both of the aforementioned concepts, the task manager resembles that demoed by Apple in the OS 4 release conference, so you get that Apple feel without actually owning an Apple device.
This app is a Task Manager/Swicther look & feel a video from iphone 4.0..
