Apple released a beta of the iPhone OS 3.2 SDK to developers last week so they can get a jump on making existing or new apps ready for the iPad. That version of the iPhone OS is made specifically for the iPad, and, as developers comb through the APIs, resources, and function calls, they are finding references to capabilities Steve Jobs never mentioned during the device's unveiling.

We have already heard about how the Contacts app contains a full UI for taking photos, suggesting some kind of camera hardware was at least considered during the design stage of the iPad. Details of what appears to be a fairly complete video conferencing or video calling implementation are also contained within iPhone OS 3.2. Sources for Engadget turned up references to functions for accepting or declining a video conference, mirror-imaging a video feed (useful for webcams), and running a video call full-screen or within a pop-over view.
