Google+ App for Apple iPhone iOS

Google released today Google+ app for the iPhone, the long awaited application for the iOS – unfortunately released with seemingly a lot of bugs and looks like a half baked attempt to quickly release the application on both platforms – Android and iOS.
As of now, Google+ for iPhone is available only for customers in USA, the app seems to be blocked for download for international users. Same applies to the Android version of the same app, which up until this day is only available to the USA users only.
