ok... i just saw on macrumors that is said airplay had been pulled from the iPhone 3g in iOS 4.2
but what is airplay, which devices does it work with... and since it seems like streaming video, will it let me (finally) watch hulu on my ipod touch?
You can watch hulu on your ipod touch by downloading the hulu app. I have the app and it works but you have to pay monthly. Sorry Hulu won't let you watch it on any device if you don't pay. You can only watch it on your computer.
