The Google+ iPhone App has finally been approved and is ready to download for free from the iTunes App Store.

Features of the App include:

Circles: that let you share the right things with the right people

Stream: where you can get updates from your circles or see what people are saying about things nearby

Huddle: super-fast group messaging for everyone in your circles.

Share just the right stuff, with just the right circles, Google Senior Vice President Vic Gundotra posted on his Google+ page.

Google boasts 10 million users of Google+ so far but it has not revealed how many were using the site on mobile devices or how many had downloaded the well-received Android app.

The App has all the main features and is similar to the Android version but it does not have the hangout feature that allows group video chat between groups.

The Google+ iOS app works with any iPhone and iPod Touch running iOS 3.1 or newer.
