Enable Multitasking Gestures
When Apple released Xcode 4 to the Mac App Store, it also exposed the ability for anyone to enable the multitasking gestures on the iPad. Once enabled, you can use five fingers to swipe up and down to reveal the multitask bar, left and right to navigate through open Apps on the multitasking bar. You can also perform a five finger pinch to close the App you are in and return to the home screen. To enable multitasking gestures, you must first purchase Xcode 4 from the Mac App Store ($4.99) or simply download it from the Apple Developer Connection (ADC) if you are already a member. Then launch Xcode 4 and select the Organizer tool from the Window menu (or click Shift+Command+2). Attach the iPad to your Mac and click on the enable development button. Log on the the ADC and click through the error messages if they are presented. Finally, on the iPad go to the General setting in the Settings App and you will notice a new setting near the bottom labels “Multitasking Gestures”.

That's great for preserving battery life of iOS devices, but if you're like me you keep an iPad or iPhone alongside you full time while working as a control panel for Pandora, podcasts, and email, and having the screen lock after a few minutes of inactivity is annoying.
