Google+ Support Pages for the Rest of Us: BlackBerry, Nokia, Windows Phone

If you have an iPhone running iOS 4 (or newer) or an Android phone running Android OS 2.1 (or newer), accessing Google+ is a matter of downloading and installing the appropriate free app. However, there is no app for an iPhone running an older version of iOS, an Android phone running an older version of Android or some other phone (Nokia with Symbian, Windows Mobile or Windows Phone). If your phone is in this last category, Google has a support page to help you out.
