Apple shuts down App Store end-runs for rejected appsThe coming iPhone-vs.-Android fight will be drawn along clear lines: Keyboard versus touchscreen. And for phone applications, open bazaar versus walled garden. While Google talks up the openness of its platform, Apple keeps plugging leaks through which iPhone app developers can thwart Apple's ruthless management of its App Store. The latest: Podcaster app developer Alamerica had been rejected by Apple. Someone at Alamerica figured out a workaround: They could hand out ad hoc licenses — meant for development and testing — in return for a $10 donation.Not only did it end-run the App Store, it cut Apple out of its 30 percent take on the fee. No more, though. Apple has shut down access to the ad hoc license system. I wouldn't go so far as to claim Apple's iron-fist approach will cause consumers to switch phones. But there's an obvious angle for Google: Play up the goofy apps like Pull My Finger that Steve Jobs wouldn't touch. Because if you've ever watched a bunch of drunk twentysomethings playing with their phones in a nightclub, you know that stupid and entertaining often beats pretty and functional.
