Apple has seeded iOS 4.3 to developers for both mobile devices and the Apple TV.
It brings new multi-touch gestures to iPad users, and the Apple TV update will allow AirPlay video from third party apps, according to “9to5Mac” (http://www.9to5mac.com/). “MacStories” (http://www.macstories.net) adds that through a new preference in the Settings app on the iPad, users can now set the behavior of the button to a mute switch or rotation lock.
And “Redmond Pie” (http://macte.ch/xJAdB) says that iOS 4.3 will bring the “Personal Hotspot” feature to all iPhones in March this year. The feature was introduced yesterday with the announcement of the Verizon iPhone.
