Change the conversation.
It’s not your everyday IM experience. With Yahoo! Messenger for iPhone, use voice and video calling to connect with your IM friends in brand new ways. Make free voice calls to your Yahoo! Messenger friends, or make low-cost voice calls to a land line or mobile phone. See your friends live and in person with video calling from your iPhone.
More fun stuff you can do.
Multi-tasker? You’ll love this. Get instant notifications when a new message arrives, even if the app isn’t open. Let Yahoo! Messenger run in the background while you run a different app. Include your Windows Live friends in your conversations, and connect with Yahoo! Messenger buddies whether they’re on a PC or mobile.
