Trouble with the pinch gesture is the iPhone. The gesture is impossible to use with one hand, and even with two hands, it's still rather awkward on a small (sub-7") screen. Remove the iPhone home button in favor of this gesture and you ruin the user experience. Leave the home button and now we've broken consistency with the iPad (which is one of the main selling points on the iOS ecosystem). Not saying they can't drop the home button, they'd just need a more practical way to do it (for example, webOS/BBX/Win8-style edge swipes)
