Apple has released a beta version of iOS 4.3 to developers via the iOS Dev Center, bringing a few dozen bug fixes and features for the third and fourth-gen iPod touch, iPhone 3GS and 4, iPad and Apple TV.
Among the noteworthy changes is the addition of four and five-finger gestures including the ability to pinch to return home, swiping up to reveal the multitasking tray, and swiping left or right to switch applications. There’s also a software option to change the iPad’s side switch back to an orientation lock.
AirPlay, which was introduced in the previous 4.2 update, now supports video streaming in third-party apps and AirPlay functionality has been added to the Photos app. The Personal Hotspot feature seen on the CDMA iPhone 4 is present, as is a new FaceTime icon and support for fullscreen iAd banners.
Some users report that the gestures aren’t functioning properly, so hopefully everything is sorted by the time 4.3 goes live.Boy Genius Report has published a changelog with various fixes, for Bluetooth, Wi-Fi, and Telephony, as well as the calendar, Exchange, fonts, keyboard, mail, messaging and more.

Will Apple launch iOS 4.3 update for Verizon iPhone next month? Apple recently showed up developer version of its next iOS software update iOS 4.3 beta. The new iOS update incorporates a pack of innovative features, Apple said last week. Apple is yet to announce iOS 4.3 release date.
Apple showed off iOS 4.3 beta’s 3G hotspot compatibility, multi-touch gestures and several other new features. Does iOS 4.3’s 3G hotspot facility translate that the software update is specially designed for Verizon iPhone?
We have enough reasons to think so; first of all, AT&T never extends 3G hotspot service for Apple iPhone. Meanwhile, Verizon Wireless does. Evidently, a Verizon iPhone is in the offing. Early week next month, you can buy a CDMA iPhone from a Verizon Wireless store.
Furthermore, iOS 4.3 beta’s multitouch gestures feature implicates that forthcoming Apple hardware upgrades like Apple iPhone 5 and iPad 2 will no longer carry physical buttons. Apple is on way to remove physical buttons from iPad and iPhone. The device will instead work on iOS 4.3’s special multitouch gestures.
According to Apple sources, a four finger multitouch gesture on iPad or iPhone touchscreen will bring you the multitasking tab. You can switch between apps there. Similarly, a five finger multitouch gesture will draw you back to home menu, i.e. no further need for a physical home button.
Meanwhile, some reports revealed that hackers have successfully developed PwnageTool Bundle jailbreak for iOS 4.3 beta on iPhone 4. But developers can only run iOS 4.3 beta jailbreak now. Once iOS 4.3 release is realized, the iOS jailbreak will be available for public.”
