Apple released iOS 4.2 beta 3 to developers yesterday. Reports from around the Web indicate that beta 3 improves performance, fixes bugs, and adds some small new features, including:
However, one of 4.2's most exciting features has been removed from the latest beta. MacStories was first to notice that Apple removed AirPlay support in the native YouTube app on iOS 4.2 Beta 3. There's been no word on the extent of AirPlay's removal or the reasons why Apple did it.
I suspect that its removal is only temporary. AirPlay -- which allows you to stream music through your house wirelessly -- is a key new feature (along with printing) of iOS 4.2 and one that Steve Jobs demo'd at the company's annual September iPod event.
It should be noted that Apple makes it easy to enroll as a developer and receive access to these early builds.
