Alongside the iPad 2 being announced today, Steve Jobs with the help of Scott Forstall unveiled iOS 4.3 to the world. New features in the update include the Nitro Javscript engine from Safari on OS X to make browsing super sweet, new iTunes Home Sharing that lets you play content from iTunes to your iOS device over WiFi, new AirPlay features that we saw in the iOS 4.3 betas such as the ability for App Store apps to share audio and video. For the iPhone only, iOS 4.3 adds the personal hotspot feature but for only the GSM version and for the iPad it adds Photobooth and Facetime to take advantage of the new camera on the iPad 2. Oh and Apple is giving us choice of whether you want the switch on the side to be for locking the screen rotation or for it to be a mute switch.
iOS 4.3 will be a free download available on March 11 for the iPhone 4 (GSM), 3GS, iPod Touch 3rd and 4th gen and both iPad models.
