Apple has released its new operating system, iOS 4.3. The new download, available via iTunes from the company’s website, comes two days earlier than Apple had initially planned.

New developments in the software include significantly faster web browsing, because the company has updated the way iOS handles Javascript.

It also now allows content to be shared around the home via a user’s wifi network, and includes enhancements to AirPlay so that enabled Apps and photos can be displayed on a big screen via Apple TV.

Perhaps the single biggest update, however, allows iPhone users to share their data connection via WiFi; the hotspotting, a feature that Google’s rival Android operating system has included for some time, can be shared by up to five other users. Bluetooth and USB can also be used to share the data connection.

iOS4.3 also allows iPad users to define whether the side switch on the device mutes the volume on the device or locks its orientation.

Apple is preparing to release iPad 2 in America tomorrow. The thinner, lighter version of the original, best-selling iPad goes on sale at 5pm local time, and then in the UK and other markets a fortnight later.

The new operating system was announced during the iPad 2 launch. Software experts who have examined iOS4.3 suggest that it contains evidence that the fortchoming iPhone 5 could be powered by the A5 processor used in the iPad 2.

iOS 4.3 can be applied to the iPhone 4, the iPhone 3GS, the iPad, and the third- and fourth-generation iPod Touch.
