iOS 4 is the operating system for iPad (along with iPhone and iPod touch). It lets you browse, read, and see everything just by touching the screen. It includes all the powerful, innovative, and fun built-in apps you use every day, many times a day. And it’s the platform on which more than 65,000 other amazing apps have been created for iPad. It’s highly secure, stable, and responsive, and it’s made to work seamlessly with the iPad hardware. iOS 4 is the reason no other device has yet come close to iPad.
