What really happened
Read Tom Clancy...
Apple wanted to find a leak. If they did in fact do this on purpose, based on the Arstechnica article, then they took the calculated risk of what that information would do to their stock price, IF it was actually leaked, and ONLY if it were leaked. Seeing how their stock has performed recently, and will probably perform after the JUNE launch of the iPhone, they probably felt it was worth it to find someone who was in violation of their contract.
Sorry, if you really believe this, then you have no idea the kind of rules that regulate the behavior of publicly traded companies. Knowingly putting out false information that would almost certainly affect billions of dollars in market cap is not only stupid, but highly illegal. As Apple executives, they would essentially be maninpulating the market based on lies, and the SEC views such actions as crimminal offenses. There is no way in hell that the email came from Apple with an official stamp of approval.
Now this is just speculation, but it is far more likely the fake news was the result of hedge fund and option traders, who do quite routinely circulate fake news to manipulate markets (refer to Cramer's admission as a former hedge fund manager how commons such practices were).
It is probably no coincidence that option calls for May are expiring on Friday. Apple has been a victim of sustained bear raiding over the past year by option traders (again, see Cramer's take for insight into the bear raiding) and just 3 weeks ago, it would have been highly doubtful that APPL would be trading around $110 per share.
What happened was that a lot of people shorted AAPL and bought a lot of puts - essentially, they were gambling that AAPL would be trading below a certain price by Friday, May 18th. But what happened in the last 2 weeks is that the stock broke through the ceiling, setting all-time high 9 consecutive trading days. That meant that a lot of people who bought those put options where suddenly deep under water.
So say you bought a single May put option contract at a $90 strike price. When you buy a put option, you pay for the right to sell 100 shares of AAPL at $90. You have to exercise that option by May 18 (3rd Friday of the month) or it expires and becomes worthless. If AAPL fell to $85 by that date, then you could exercise the option and buy 100 shares at $85 and sell it immediately at the guaranteed price of $90 (the strike price).
But what happened was that AAPL zoomed up to $110. Suddenly, a lot of people who had expected AAPL to drop to $90 were facing the prospect of having to sell AAPL at $90 a share and cover their puts by buying shares on the open market at $110 a share - a instant loss of $20 a share.
Or you watch as your $90 put options expire on May 18 because no one is stupid enough to want to sell AAPL at $90 and buy them for $110/share. You lose 100% of the money you spent buying those $90 put options that looked quite reasonable 3 weeks ago.
So what is a hedge fund operator to do? You put out a fake email designed to have the maximum negative
but believable PR, i.e. the iPhone and Leopard being delayed. That causes a market panic, the stock drops, and the hedge fund traders can at least unload their put options and take a far smaller loss. If the drop is steep enough, you could even turn around a quick profit on the drop.
Don't believe me? Just check out the May 2007 options chart at finance.yahoo.com

Look at how many open contract there are for put options at $90, $95, and $100. We are talking about tens of millions of shares here that people were gambling that AAPL would drop to $90, $95 or $100 by tomorrow. Look at the bid prices for those put option.
N/A - completely worthless.
Now look at the asking price - not zero but close to it, i.e. people are still trying to sell their worthless put options by tomorrow. A lof of people who were counting on AAPL to lose steam are going to be losing many millions of dollars tomorrow.....
Sorry if this explanation is long and complicated, but this scenario is far more plausible than a ridiculous attempt to root out a leaker. Apple gains nearly nothing rooting out a single leaker while risking billions of dollars of loss in market cap and exposing the entire board and executive hierarchy to criminal wrongdoing. It just doesn't fly no matter how much you hate Steve for his secretiveness, but the idea that this was a vindictive insider plot by Apple is 100% ridiculous.
