Engadget has just confirmed with "extremely trusted sources" that iPhone OS 3.2 contains rudimentary support for video calling, which could explain that mysterious space at the top of the iPad's leaked pictures they received.
Engadget's sources said there are hooks to accept and decline a video conference, flip a video feed (which suggests a front-facing camera) and -- most importantly -- run the video call in either full screen mode or in just a portion of the screen. Video calling in just part of the screen (the other part left open for other apps) would be indicative of some basic type of multitasking.
Engadget also confirms that "iPhone OS 3.2 supports file downloads and local storage in the browser, which means you'll be able to pull files off the web and use them in other apps, and there's at least the beginnings of SMS support buried within the code."
While our sister site is quick to point out that it's not sure if any of the code will ever be implemented, they're starting to get the feeling that Apple didn't tell everything there is to know about their latest creation...
