IF YOU CANNOT DOWNLOAD the Google Plus app in your country after browsing to Google's recommended site at m.google.com/plus, feel free to point your Android handset at my blog and click on the link to download the Google+ app. The app normally downloads to your SD card where you can install it from the phone. I changed my Settings to facilitate the installation by gong into "Application Settings" and selecting the option to "allow installation of non-Market applications". Then I selected "Manage Applications" and tapped the top of the screen until I found "Google+". Tapping the app starts its installation.
