Apple just seeded iOS 4.3 Beta 2 (Build: 8F5153d) for iPhone 4/3GS (Size: 679MB), iPod Touch 4G/3G, iPad Wifi+3G (Size: 607MB) and Apple TV 2G. iOS 4.3 Beta 1 was released last week in which Apple introduced some new iOS features like Personal Hotspot, AirPlay for 3rd party apps and new multi-touch gestures for iPad.
Along with iOS 4.3 Beta 2 release, Apple has confirmed that the multitasking gestures for iPad will not be available to end-users in the final release. However, developers are encouraged to test them but first they have to enable the multitasking gestures on their iPads by using "Use for Development" option in Xcode.
This beta release contains a preview of new multitasking gestures for iPad. You can use four or five fingers to pinch to the Home Screen, swipe up to reveal the multitasking bar, and swipe left or right between apps. 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.
Developers are encouraged to evaluate any existing interactions in their applications for potential sources of interference.
As a whole, iOS 4.3 Beta 2 don't come with any new exciting features but it do come with many more bug fixes and stability patches. Like other betas, you can download iOS 4.3 Beta 2 if you are enrolled in iPhone Developer Standard or Enterprise Program.
