Zephyr by chpwn has been updated to version 1.0.2-1 with a few more enhancements. For starters, you can now disable gestures in any app you choose. This is handy for games and apps that may cause you to unintentionally invoke a gesture. It looks as if he's gotten help with this feature from Ryan Petrich, creator of Display Recorder, one of my favorite jailbreak apps.
Zephyr by chpwn has been updated to version 1.0.1 to add a few enhancements and fix a few existing bugs. Among the changes are fixes to disable multitasking gestures within apps such as Cut the Rope or Words with Friends where you may not want gestures to be active.
Zephyr, by jailbreak phenom chpwn, brings iPad-style multitasking gestures to the iPhone.
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 registers bezel-to-screen swipes, which makes sense given the smaller surface area of the 3.5-inch iPhone vs. 9.7 inch iPad display. While only the 2 gestures listed above are currently supported, anyone already familiar with their iPad counterparts will realize the efficiency boost they can provide.
If you're jailbroken, you can grab it now from Cydia for $2.99.
