Updated iPhone with live Video Out from Ars Technica on Vimeo.

A few days ago we mentioned Ars' iPhone expert, Erica Sadun was taking the lifting of iPhone OS 2.2's NDA as an opportunity to dump code and sift for gold. Turns out she's not only found some in the way of "hidden" TV-out features in iPhone 2.2, she's sacrificed her well earned turkey day to experiment with them. From her previous post, here's what's at work:

The MPTVOutWindow class allows your iPhone to send its video to a connected TV rather than to the built-in screen. Intended to be used with movies, the unpublished class creates a live video feed that is sent out through the iPhone's connector port. End-users will need to buy a video adapter or cable to use this functionality.

Early days still, but fairly awesome stuff. Can't wait to see what she and other developers -- not to mention Apple eventually -- come up with!
