My opinion expressed here is not intended to encourage anyone to experiment with beta software. That being said. I absolutely love iOS 4.2 beta 3! Yea, some of my apps do not work but most do. Yea, AirPrint does not operate yet. I have created folders, renamed them, multitasking works or app switching as I like to call it. I now have all (around 70) apps on one screen. That's cool. I can hardly wait for the next email from Apple notifying me that iOS 4.2 beta 4 is available for download. I believe that when iOS 4.2 is finally available to the public you will love it too.
