We know it’s important for many of you to get the latest Android software upgrades onto your phones as quickly as possible. With that in mind, we’re also introducing Test Drive, a new program that will allow consumers to take our major software upgrades for a trial run and provide valuable feedback before we launch the upgrade publicly.

More details on how to sign-up and participate will be announced on the blog soon.
