Apple today issued a second beta version of iOS 4.3 to registered developers, marking a quick turnaround since the initial beta version was seeded one week ago.
The new seed carries build number 8F5153d, up from the previous 8F5148b, and is similarly available in versions for the iPad, iPhone 4 and 3GS, and third- and fourth-generation iPod touch, as well as in a separate version for the new Apple TV.
There is no word yet on changes in the new build, but the first beta version added for support for a number of features including personal Wi-Fi hotspot functionality, new multi-touch gestures for the iPad, support for video streaming from third-party and web apps via AirPlay, and a new software option for selecting the functionality of the iPad's side switch.
Update: 9 to 5 Mac notes that Apple has clarified in the documentation accompanying the new build that the four- and five-finger iPad gestures added in the initial build will not be included in the public release of iOS 4.3 and are simply being included in developer versions so that Apple can obtain input from developers on their functionality.
This feature will not be enabled in iOS 4.3 for customers, but we are providing this preview to gather input on how these gestures work with your apps.
