No, me neither. The thought of Apple allowing a competitor to publish such an app is laughable. Google is much more open and as a result Apple has been able to publish a 'Switch to iOS' app in the Play Store.
That App is currently being hammered with one star reviews by Android fans, somewhat unsurprisingly. Something which John Gruber finds hilarious.
No John, what's hilarious is that you're prepared to accept a situation where Apple can sensor its app store to prevent this sort of app. Or any other app it takes a dislike to. A not uncommon occurrence as it turns out.
