I was running GM iOS 4.2 on my iPod touch 2G, and Airprint and Airplay both worked just fine. Now that iOS 4.2.1 is out, do Airprint and Airplay still work properly? I know that these features were removed from the iPhone 3G, and I am trying to determine if I should upgrade from 4.2 to 4.2.1 - advantages, disadvantages, etc. Thanks.
