The latest iPad/iPhone SDK not only makes it easier for developers to build universal iPad/iPhone apps, but it also appears to have support for a front-facing camera, zoom, camera flash and video conferencing. Oh, and some snazzy accept/decline buttons.
Keep in mind that the iPad SDK is the same as the iPhone SDK at this time, so we can't really know which sections of the framework are intended for which device. Not to mention that Apple sometimes leaves some stray test conditions in the code which may never make it into a final OS. [MacRumors]
