With iOS 5 Apple added some really awesome multitasking gestures to the iPad 2. These gestures also worked with the iPad 1 when iOS 5 was still in beta, but for some reason apple has decided to make it an iPad 2-exclusive feature when they officially released the new OS. I use the gestures all the time and love them. They allow me to do everything necessary to navigate through the iPad without having to touch any button.
If you are a frustrated iPad 1 owner who wants this amazing features that make the iPad so much more easier to navigate, then just follow Gizmodo’s amazing tutorial on how to enable these features. I would write the tutorial myself but then you would basically be reading Gizmodo’s same post in my own words, and I don’t feel like wasting time. Enjoy!
