Google announced the Android 4.0 Ice Cream Sandwich, its new operating system set to run on Samsung's Galaxy Nexus, on Wednesday to compete against Apple's iOS 5 operating system and iPhone 4S.

Both Google and Samsung are looking to beat Apple in an area that it is now succeeding. You see, the Ice Cream Sandwich was created to do what Apple has already perfected: unifying its iPhones, iPads and iPods with its iOS operating system. The Ice Cream Sandwich Google will do the same for Android-run smartphones and tablets. And the new features of Android 4.0 are certainly more impressive than those of its predecessors Gingerbread and Honeycomb.

Android 4.0 builds on the things people love most about Android - efficient multitasking, rich notifications, customizable home screens, resizable widgets, and deep interactivity - and adds powerful new ways of communicating and sharing, according to Android Developers blog. It includes many great features for users, including social and sharing integration, network data usage control, innovative connectivity and camera options, and an updated set of standard apps.
