Apple has just announced at today’s iPad 2 media event that iOS 4.3 will be released on March 11th.

iOS 4.3 includes a number of new features and improvements such as faster Safari mobile browser performance as it uses the Nitro Javascript engine, iTunes home sharing, AirPlay enhancements, toggle for iPad’s side switch and personal hotspot for iPhone 4 users.

Here are more details about the new features:

Faster Safari:

Apple has ported the Nitro Javascript engine used in desktop version of Safari to iOS so Mobile Safari browser in iOS 4.3 loads Javascripts two times faster.

iTunes Home Sharing:

Allows iOS 4.3 users to play music, movies and TV shows on an iPad, iPhone or iPod touch from their iTunes library on a Mac or PC over a local Wi-Fi network. This feature was previously available only on the Mac and Windows PC.

AirPlay Enhancement:

AirPlay which was first introduced in iOS 4.2, allowed iPhone, iPad and iPod Touch users to wirelessly stream digital content to Apple TV 2G. However, the AirPlay option was available only in some pre-installed apps such as iPod/Video app and YouTube. iOS 4.3 will allow users to stream digital content from third party apps and websites and also videos and photos from the Photos app.

Personal Hotspot:

Personal Hotspot feature will allow users to share an iPhone 4 cellular data connection with up to five devices in a combination of up to three Wi-Fi, three Bluetooth and one USB device. However, carriers need to support the feature. We’ve heard that AT&T is already allowing the feature for iOS 4.3 beta users.

This feature is already available to Verizon iPhone users.


iOS 4.3 is compatible with GSM iPhone 4, iPhone 3GS, iPod Touch 4th generation, iPod Touch 3rd generation, iPad and iPad 2.

Unfortunately, iOS 4.3 will not available for iPhone 3G and iPod Touch 2nd generation, which means that iOS 4.2.1 is the last iOS software update for these devices. Surprisingly, iOS 4.3 is also not compatible with the Verizon iPhone.

Release date:

Apple announced during today’s media event that iOS 4.3 will be released on March 11th.

These are just some of the new features in iOS 4.3. Most of the features were already known to us except for iTunes Home sharing and faster Safari performance. You can checkout our detailed walkthrough of iOS 4.3 features to find out about the features in iOS 4.3 that Apple didn’t mention.
