YouTube available now for Apple TV, will be on iPhone when shipping

Attention Apple TV owners, you might want to run software update. Why? Because Apple has just released the YouTube update. You might recall that Apple announced Apple TVs would soon be able to play YouTube videos thanks to a free software update (which is all part of the surprising and delighting). That update has come, and it is available for download.

Apple also announced today that the 'mystery 12th app' on the iPhone is... a YouTube viewer! That's right, no longer will you be tethered to your desk watching grown men put Mentos in Diet Coke bottles, you can do that while walking around, riding a bus, or sipping coffee at a Starbucks. The iPhone YouTube app will have a multitouch display and work over EDGE and WiFi (though I imagine it'll work best with WiFi).

Remember that YouTube has started encoding videos in H.264, so that Flash will not be needed on either the Apple TV or the iPhone to enjoy this content. 10,000 YouTube videos will be available on June 29th in this format, with more coming every week.

Update: TUAW reader Brad points out that Apple added a video of the YouTube app to the iPhone section of thier website. Go check it out.
