MySpace, the big social network that is vying with Facebook for top-dog status globally, has released a mobile version of its site designed especially for the iPhone.

MySpace has also released new statistics revealing explosive growth among mobile users: Page views of the company’s mobile site appear to have more than doubled between March and June.

Traffic blasted past 2.5 billion page views in May, from 1.4 billion in March. John Faith, MySpace’s general manger and vice president of mobile, said in an interview he expects the 3 billion number to be broken when June stats are in. That’s impressive, because the company had originally forecast to reach 3 billion by August: “We’ll blow through that, we’re seeing astounding exponential growth.”

While the iPhone still has a small overall market share among phone users, the phone is significant because its full screen and other features such as location and touch technology allow people to browse and interact more easily and fully than other phones.

And while MySpace and Facebook battle for more users, the latest battleground has clearly become mobile. While other companies such as MocoSpace were early to offer mobile-only social networking offerings, MySpace and Facebook have recently shot ahead and become the most popular social networks, as we reported two months ago.

Released in October, MySpace’s mobile site (WAP) (http://m.myspace.com) gets more than 1.7 million daily unique mobile visits in the United States alone, after breaking 1 million in March. The site is seeing 250,000 additional uniques every month.

Facebook is offering its own application at the iPhone App Store.

Here are some of the main features of the MySpace application. MySpace said a key feature was the ability to upload photos directly from the iPhone to your MySpace profile:

— Camera integration and optimized photo management allowing users to snap, sort and upload pictures anytime and anywhere.
— The ability to stay connected with friends through a full messaging interface.
— Pinch, flick and swipe your way through the MySpace navigation using standard iPhone touch support.
— Real-time friend, status and mood updates.
— Feedback mechanism letting users contribute to future iterations of the product.
— Available in 12 languages by the end of this month.

You can download it from Apple’s App Store on iPhone and iPod touch or at http://www.itunes.com/appstore/”www.itunes.com/appstore/.

Other traffic numbers:
— Projected usage to hit 3 to 5 million unique global users per day by the end of 2008.
