Not stoked on Skype or FaceTime? Looks like you've got another option, bub. That overhauled Yahoo Messenger app we told you about 48 hours ago is now live in the App Store, offering multitasking on the iPhone 3GS and iPhone 4, 3G / WiFi video calling (iOS to iOS, iOS to Android or iOS to PC) and instant notifications. Users interested in making voice calls can also tap into their bucket of Yahoo Voice Phone Out minutes, but it'll only work in America, France, Germany, Spain and Singapore at the moment. Hit that source link to get your download on, cool?
