iOS 4.3 Released prior to its launch date

Yes you have heared it right!! Apple has released its new operating system, iOS 4.3, two days earlier than initially planned. iOS 4.3 is now available as a free update on iTunes for iPad, iPhone 3GS, GSM iPhone 4, and third- and fourth-generation iPod touch.

 

iOS 4.3 brings several new features to Apple devices including AirPlay for all third-party apps and personal hotspot support.
The feature first appeared in iOS 4.2, allowing Apple's iOS apps to stream audio, video, and photo slideshows to a second-generation Apple TV.

The new OS also brings support for creating a personal hotspot, a feature that allows iPhone 4 to act as a portable WiFi router for up to five devices.

Another addition is iTunes Home Sharing, which will allow iPhone, iPod touch, and iPad users to stream their iTunes media from a Mac or PC on the same WiFi network.

Apple also claims to have made Safari's JavaScript performance up to twice as fast in iOS 4.3.

The company reportedly also seems to have relented to user discontent on changing the behavior of the iPad's side switch. When iPad launched last year, its side switch acted as a display rotation lock. However, the release of iOS 4.2 last November changed the switch from a rotation lock to a mute switch, without offering users an option to change it back.

In iOS 4.3, the switch remains default to muting audio, however, the company has added a new preference to the Settings app that allows users to enable the rotation lock behavior instead.

The only thing missed in iOS 4.3 is multitouch gestures.
