When Apple released the first beta version of iOS 4.2, we were excited about the AirPlay feature as it allowed users to stream content from apps like YouTube, Netflix, Mobile Safari that implemented the video playback controller to stream audio and video content to the new Apple TV.
However, when iOS 4.2.1 was released finally on Monday, we were disappointed to find out that the AirPlay feature was only available on the iPod and YouTube app and it was possible to only stream audio from third party apps.
