Apple has released iOS 4.3. The update is available via Apple’s iTunes application.
New 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. With a tap you can enjoy all the media in your iTunes library wherever you are in your home. You can stream a movie from your Mac in one room to your iPad in another or stream an iTunes mix to your iPod touch from the office to the kitchen.
iOS 4.3 includes enhancements to AirPlay, the wireless technology that allows users to stream music, photos and video to Apple TV. With iOS 4.3 you can stream additional content including video from third party apps and websites, videos from the Photos app and previews from the iTunes app to your TV. AirPlay also allows you to bring photos to life on the TV screen by using one of the new slideshow transitions, or shoot a video on your iPad 2, iPhone or iPod touch and stream it directly from the Photos app to Apple TV.
The new Personal Hotspot feature in iOS 4.3 lets you bring Wi-Fi with you anywhere you go, by allowing you 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. Once the feature is enabled, a status bar displays how many devices are currently connected. Every connection is password protected and when not in use Personal Hotspot turns itself off to save battery life.
iOS 4.3 is available as a free software update. It’s compatible with iPad, iPad 2, iPhone 3GS, iPhone 4 (GSM model), plus third and fourth generation iPod touch.
