Yahoo rolled out a new Messenger app for iOS that includes support for the iPad 2. The tablet-optimized app will let you make voice and video calls using the front-facing camera. Yahoo Messenger has a wide install base and you will be able to make video calls to any device with a camera and a compatible version of the messaging app. Besides video calling, Yahoo Messenger will also send SMS messages for free. The SMS feature is a quick way to message to a friend, but you have to remember these messages come from your Yahoo account, not your mobile phone number.
