According to a post at Google’s Nexus One Blog, the “official” Android 2.2 (“Froyo”) update for Nexus One is being rolled out over-the-air (OTA) even as we speak.

According to the post, “Starting today <06/28/2010>, Nexus One users will begin to receive the Android 2.2 (codenamed Froyo) over-the-air software update on their phones. <...> 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.”

Google goes on to say that the upgrade will be a gradual process. “This update will be rolled out gradually to phones – and most users will receive the notification by the end of the week.”

Of course, this update only applies to phones that are running Google’s stock Nexus One ROM. Those of us using custom ROMs (such as CyanogenMod) will have to wait for those ROMs to be updated by their respective ROM developers.
