Apple has just released the iOS4.3 update, which was not scheduled for release for another 2 days, and is available to download via iTunes now.

The iOS update brings:

  • AirPlay Enhancements – with third party Apps and websites now able to use Airplay
  • Safari Performance updates with faster Javascript
  • iTunes Home Sharing – allows you to play your entire iTunes library from anywhere in the house
  • iPad side switch configurable as mute or rotation
  • Personal Hotspot for iPhone 4

The Personal Hotspot requires a supporting hotspot tethering plan from your carrier, and only recently clarified it only works with up to three devices over Wi-Fi, three devices over Bluetooth, and one device over USB.
