Apple originally set iOS 4.3 for release on March 11, 2011 to coincide with the iPad 2 release. iOS 4.3 has now been released a few days earlier and is available for immediate download.
iOS 4.3 brings numerous feature enhancements to iDevices such as AirPlay video compatibility for third-party apps and websites, Safari speed improvements, Home Sharing, and a new option for customizing the iPad’s side switch.
iOS 4.3 also delivers the highly anticipated Personal Hotspot function to the GSM iPhone 4.
The update is available for the iPad, iPhone, and iPod touch, and users may update their devices by connecting them to iTunes and clicking “Check for Update”.
Jailbreakers/Unlockers should avoid iOS 4.3 until further notice.
