Today at Google I/O the next version of Android, that is 2.2, was made official. The biggest story here is speed (oh, and a little piece of software called Flash 10.1). Google claims that the web browser of 2.2 is the fastest of any mobile device. They are also promising 2-5x faster system speed, which we’re all in favor of. Additionally, there is better Exchange integration, new ways to manage apps, and a built in WiFi tethering app. Here are a few screenshots comparing the two systems. You’ll notice modest changes: new menu items in some programs, an updated home screen (which OEMs are going to skin anyhow), a new navigation panel, and some other goodies.
