Apple has released the second beta version of iOS 4.3 to its paid developers. Listed as build number 8F5153d, it is unclear what has changed in the new version from the first, which brought AirPlay functionality to Safari and third-party apps, the Personal Hotspot Internet sharing feature, an option in the Settings app to choose whether the iPad’s side switch acts as a screen rotation lock or as a mute switch, and new four- and five-finger gestures for the iPad. Notably, documentation released alongside the new beta indicates that the aforementioned gestures will not be part of iOS 4.3’s public release, but are instead included in order to gain developer feedback, and the release is accompanied by a new preview build of Apple TV Software 4.3. Separate versions of iOS 4.3 beta 2 for the iPad, iPhone 4, iPhone 3GS, third-, and fourth-generation iPod touch are available as downloads for paid iOS developers from Apple’s iOS Dev Center.
