For my iPhone using friends: the Google+ iPhone app has been submitted to the App store (no not today, sometime prior to today) and is awaiting approval.
The quote only expresses that the app will work on the iPhone, but Erica later stated that it will be available for all iOS devices. This means that the iPad will be receiving a specific app designed for its larger screen. The Google+ service is still only available for exclusive invited members only, so unless you have received one of those invites, you will have to wait for Google+ to go public before you can try the app out for yourself.
