Google+ is expanding its mobile reach with today's debut of an iPhone app dedicated to the new social networking site.
Up until now, clever iPhone users could have added a link to their home screens, but that still would have gone straight to the browser window. (Anyone who did this was also likely already a diehard Google+ addict.)
But that isn't the case anymore. Google has released, as expected, a free app that is available immediately for iOS 3.1 and higher. The technical requirements are that this app only works for the following devices: iPhone 3G, iPhone 3GS, and iPhone 4.
The mobile interface isn't much different from the ultra-simple and clean desktop version. The app features focus on Circles for sharing particular items with the "right people," the Huddle for group messaging, and the Stream, which is basically a news feed from all of a user's Circles.
Naturally, there has already been a dedicated Android app for some time now, downloadable for free from the Android Market.
The Goog's foray into social networking debuted a few weeks ago, and it is still in invite-only mode. Nevertheless, the Mountain View, Calif.-based company asserted that Google+ already retains 10 million active users.
