You don't know that it was a stunt. It is possible they sold many phones. I really doubt that 8600 likes translates to sales numbers. There is no way of knowing if Google sold 500 or 2 million phones before it ran out of stock. It is also possible that LG does not have the production capacity meet demand. It would be a marketing stunt if Google is intentionally creating a supply shortage, but I doubt that is Google game. Then again, we won't know until Google releases a statement about how Nexus 4s have been sold.
