If you think for even one moment that your decision will have any effect on Apple you are sorely mistaken. You are cutting your own throat to make your point. Steve Jobs can be very vindictive when he wants to be (read the book iCon). You may find yourself on the outside looking in, banned all together from ever submitting an iPhone app again.

Developing for the jailbroken market would be another big mistake. It would only serve to further alienate you from Apple.
