With more than 160 million iOS devices worldwide, including over 100 million iPhones, the growth of the iOS platform has been unprecedented. iOS 4.3 adds even more features to the world’s most advanced mobile operating system, across three blockbuster devices—iPad, iPhone and iPod touch—providing an ecosystem that offers customers an incredibly rich experience and developers unlimited opportunities.
iOS 4.3 Features
AirPlay Enhancements : With iOS 4.3 you can stream additional content including video from third party apps and web sites, 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 stunning 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.
iTunes Home Sharing: 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 simple 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. With Home Sharing on your iPad, iPhone or iPod touch you’ve got your entire iTunes library in your hands wherever you are in your home.
Personal Hotspot for iPhone 4: 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
iPad Side Switch: Customize the switch on the side of your iPad to lock the screen rotation or mute the volume. So you can lock your iPad display in landscape or portrait. Or quickly go from volume on to volume off. Just configure the side switch in Settings to toggle between your options.
