Google Officially Announces Android 2.2 “Froyo”

Google announced Android 2.2 "Froyo" at I/O, and the big addition is just-in-time compiler, which brings a 2-5 time speed bost to the system. There are also 20 new enterprise features, including better Exchange integration and device administration APIs, as well as a new device backup app that'll let you transfer personal data to a new device. Android 2.2 also features a new cloud-to-device messaging API that Google called "much more than a push notification service designed to make up for a lack of basic features like multitasking," and of course, WiFI tethering. The company used the WiFi tethering to get a WiFi iPad online during the demo to great cheers. Google also demoed a new Javascript engine in the Android browser, which is billed as "the world's fastest web browser," and a Chrome browser plugin that allows you to send directions from Maps on your desktop directly to your phone.
