Good news, Nexus One owners. Google is finally rolling out Android 2.2, codenamed Froyo, to your devices in an over-the-air update. The latest version of the mobile platform brings several performance improvements to the table, as well as new features like support for push notifications, better support for Microsoft's Exchange software, a streamlined Android Market interface, and the ability to turn your phone into a portable Wi-Fi hotspot that can be shared with up to 8 devices.

Android 2.2 also brings faster app-switching and support for Adobe Flash 10.1, allowing you phone's web browser to fully run websites that use Flash for navigation, games and video. In order to access the update, you will receive a message on your phone's notification bar. Just download the update, wait for it to install, and you should be all set. The update will be compatible with most Android phones released in 2010. If you have an older Android smartphone, like the T-Mobile G1, don't expect to get Froyo, as its hardware is said to be too limited to provide full support.
