Fresh Yahoo Messenger 2.0 has come along with several new functions such as video calls and stream live video one-to-one.
Other new functions also include voice calls, low cost voice calls, and multitasking. Now you can make free voice calls to your Yahoo! Messenger friends. Low cost voice call allows you to talk with your friends on mobile phones or land line, and make low cost international calls with Yahoo! Voice Phone Out account, but this function is available only in America, Germany, France, Spain and Singapore for the time being. And the multitasking lets Yahoo Messenger runs in the background when you use another iPhone app.
The new Yahoo! Messenger 2.0 supports iPhone 3GS and iPhone 4 running on iOS 4.1. If you’re interested, jump to iTunes for more details.
