Apple has released the fourth beta of the iPad SDK 3.2. The previous beta was released two weeks ago. So far there have been no new discoveries. The fourth beta fixes the bookmark function in Safari. The Camera tab has been removed from the Photos applications. Many people believed this tab was the best evidence that the iPad will have a camera after all. But Apple says the following:
“The Camera tab represents photos available via the Camera Connection Kit for iPad, and is not relevant for the Simulator. The Camera tab will disappear after a few seconds.”
As a paying user of the SDK you have access to the changelog and the SDK itself via the iPhone Dev Center.
