Does Apple do controlled leaks? Of course, any company which is able to keep secrets in the first place does.

For the iPhone 4? Absolutely not, the only other model which changed iPhone as much as the 4 was the X, Steve was still alive for the 4 and there is absolutely no way he would have approved just leaving it in a bar for hype.

Steve Jobs wanted to be the person who showed that to the world. Remember the first MacBook Air? Steve lived for that moment.
