Google+ is the next thing, regardless if it will be big or not, as nobody can predict its success. El Goog’s answer to Facebook is rolling out slowly but surely and, as such, clients for popular platforms are coming out.
Google has released the official Google+ application for Apple’s iPhone. It’s free in the iTunes AppStore and will bring you all the features you’d expect from an official client. You’ve got access to your circles letting you share things with some, get updates from people using stream and send group messages to your circles using Huddle. It will work on your iPhone 3G, iPhone 3GS, and iPhone 4 running iOS 4.0 or later.
