Early tests have indicated that FaceTime for OSX works already very well in its current beta. If you would like to call another iOS device from your Mac, however, note that iOS 4.1 is required for a successful connection.
If you try to call a device with iOS 4.01 installed you will be presented with the following error message: “User needs to update to the latest version of FaceTime.”
So go grab your copy of FaceTime and be sure to update your iPod Touch/iPhone to iOS 4.1.

Thanks very much for the info. I was getting that message but I couldn’t figure out what did it mean. Instead of “update FaceTime” Apple should announce “update your iPhone IOS version to 4.1″.
