iOS 4.3 has been released to developers, the key new features being:

  • WiFi Hotspot capability, shown with the recent release of the iPhone on Verizon was the option of a Wifi Hotspot. This will almost certainly require carrier activation though.
  • 3rd party AirPlay capability – developers can start testing the sending of audio andvideo to AirPlay supported devices in their Apps.
  • iPad slide switch updated to allow user configurable option of Mute or Orientation Lock – this will appease many users who were angry at the change of the button functionality.
  • iPad multitouch multitasking gestures – e.g. swipe up to reveal the multitasking bar, and swipe left or right between apps
  • The Photos app has also gained new AirPlay functionality for photos and videos
