Update: Chpwn has decided to discontinue ProSwitcher given that Multitasking has come to iOS 4.
Here, is a cool Cydia app that would reminds us how much we love jailbroken iPhones. While missing the launch of Palm Pre in India, here comes ProSwitcher that brings the WebOS app switching interface to the Apple iPhone. Once activated Pro Switcher lets you double click on the home button (or other combinations that you can choose from app settings) and enter the card mode to switch apps. The app is currently in beta but works like a charm with backgrounder. The best part has to be the fact that this lets you switch between native apps, cydia apps and app store apps!
Multitasking + Palm Pre UI is killer enough to command good price on Cydia store. Get it before this gets paid ;).
Here, is a quick video demonstrating the amazing app.
