By Darrell Etherington, GigaOM The iOS 4.3 beta, despite being covered by Apple’s NDA, is leaking signs of new hardware and software features like a sieve. The latest find is support for multi-touch gestures on the iPhone. Apple is beta-testing these gestures publicly for the iPad in 4.3, but new evidence suggests private testing is going on for the iPhone, too. Might the presence of these features suggest a buttonless future for iOS devices? According to Engadget, iPhone user Antoni Nygaard managed to activate the hidden multi-touch gesture features on his device using the iOS 4.3 pre-release software (as well as options to change the function of the iPhone’s mute button to a rotation lock, another iPad import). BGR also has screenshots of the gestures in action and the relevant Settings screen from a separate source. Nygaard’s demonstration of the feature in action can be seen in the video below. Apple dampened anticipation surrounding the new gestures for iPad when it noted, alongside the release of the second beta of iOS 4.3, that these would not be included in the pubic release of the update, and were intended for testing purposes only. The gestures are even less likely to make it into a public 4.3 release on the iPhone, since they aren’t an acknowledged feature of the beta. So why is the feature there? There are those who argue that it’s because Apple is going to get rid of the home button (that adorable one with the white rounded rectangle) in future hardware iterations of the iPhone, iPad and iPod touch. It’s true that the gestures replace navigation duties normally handled by the home button, making it possible to fully use the devices without ever touching such a button. But just because it can be done, does that mean it should?
