iOS 4.3 Beta now available for developers [Released][iPhone, iPod touch, iPad and Apple TV]

Apple has just released a Beta version of iOS 4.3 to Developers. It’s labelled iOS 4.3 beta and while we don’t now yet what new features will be there in iOS 4.3 beta 1. The beta is available for iOS devices and the second generation Apple TV. Supported iOS mobile devices are iPad, iPhone 4 and 3GS, iPod touch 3rd and 4th gen. Build number is 8F5148b. A pre-release version of the Apple TV software has been provided to test AirPlay functionalities with 4.3 apps.

It looks like iOS 4.3 has some cool new gestures built specifically for the iPad. 4 & 5 finger gestures; pinch to the home screen, swipe up to reveal multitasking tray, swipe left/right to switch apps.

Test Multi-Touch Gestures for iPad
This beta release contains a preview of new Multi-Touch 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. We are providing this preview before releasing them to the public to understand how these gestures work with your apps. Test them and give us your feedback on the Apple Developer Forums.

It looks like Apple finally dropped support for the 2008 iPhone 3G. The device is indeed not listed on the iOS developer website, and nothing makes us think that future beta versions will be released for that model. The latest OS for the iPhone 3G may be iOS 4.2.

iOS 4.3 brings Personal Hotspot to GSM iPhones.
