Following the recent launch of Google+ on iPhone, the official app is now updated to include iPad and iPod Touch. Keep in mind that the iPad version is just a zoomed-in version of the iPhone app; presumably a native iPad version that takes advantage of the increased screen real estate will be forthcoming.

Improvements in this update for all iOS systems include notifications added to circles and huddles along with stability improvement.

Google+ is a free download for iPhone, iPad, and iPod touch in the iTunes Web Store.
