9to5Mac rediscovers evidence that the iPad 3.2 SDK shows hints of video conferencing. This was first discovered shortly after the SDK's release in January:
We're told that 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. That means you'll be able to chat and do other things at the same time, which could mean there's at least some type of multitasking going on here.
The iPad, of course, does not come with a built in camera making video conferencing an impossibility with the current revision. Apple must have been testing video conferencing as a possibility but ultimately decided against it.
