Make Video And Voice Calls With Tango On Your iPhone and Android Smartphones

Tango is a new and FREE mobile-to-mobile video calling service [Think Fring only better]. Tango currently supports the iPhone 4, iPhone 3GS, and 4th generation iPod touch as well as devices running Android 2.1 and higher.

Tango became the #1 free social networking app, knocking off Twitter, Skype and Facebook in the App Store going viral in nine countries including the United States, Hong Kong, France, Taiwan, Spain and South Korea. And Tango announced this week its 1 millionth download from the App Store and Android Marketplace--and it merely took a couple of hours on launch date to do so.

No wonder Skype, Facebook, and Twitter are all scramming to integrate and partner with each other or with other tech companies to provide more features for their products, they've all be one-upped by a newcomer named Tango.
