I did as well. It sounded exactly like Steve Jobs. At the time, I didn't know what Steve Jobs sounded like so it didn't quite click until I saw one of his keynotes. He even gave me his direct line to call him back regarding one of my apps. I called him back and left him a message. I'm half tempted to dig up my cell phone records and find the number so that I can listen to his answering-message. But I would think Steve Jobs would have a secretary answering his phone? Don't you? So maybe it wasn't him.
