chpwn has released an enhancement to the iOS's multitasking feature. The tweak is called "Zephyr" brings new multitasking gestures that are inspired by Meego's Swipe interface (mobile OS running Nokia N9).
"Zephyr is multitasking gestures for iPhone and iPod touch. From swiping up to show the multitasking switcher or quickly swiping to a different app, Zephyr is all you need to quickly and easily control multitasking."
Zephyr is currently exclusive to jailbroken iPhones and iPod touches and the edge swipes are not currently customizable to open features other than multitasking. Paul promises additional functionality through future updates.
As you can see in the video, a user just has to flick up from the bottom of their iOS device's display to open the multitasking bar. In addition, you can swipe in from the edge - just the like the iPad on iOS 5, but one with one finger - in order to move between applications.
"I think this is probably the most efficient way to multitask on the iPhone," Grant Paul (chpwn) said in his video demonstration of the tweak.
The tweak is currently available via the Cydia jailbreak application market for $2.99.
