Apple iOS 4.3 coming March 11 with iPad 2

At the iPad 2 launch event, Apple introduced the final version of iOS 4.3. It'll be a free download for all iPads, the GSM iPhone 4, the iPhone 3GS and the third- and fourth-gen iPod touch when it's released on March 11.

Here is a rundown of the new features of the operating system:

• Improvements to the Safari web browser – JavaScript performance has been improved with the Nitro JavaScript Engine.
• iTunes home sharing – you can now access all your content available on your desktop through WiFi. Stream your entire iTunes library without the need to transfer media to your device.
• Improvements to AirPlay – easier to use, slideshow options for sharing photos and apps and websites can even make use of the AirPlay function.
• Preference for iPad switch – you can now choose to use the switch on your iPad to mute the device or use it to lock its orientation.
• Personal hotspot (for the iPhone 4 only) – turn your iPhone 4 into a mobile hotspot that you can use to share your internet connection with people around you.
• FaceTime – of course we all knew this was coming to the iPad 2 – video call over WiFi with other iPad 2, iPhone 4 and Mac users.
