iOS 4.3 Released Today

Apple released the latest version of their mobile operating system iOS 4.3 today.  This is a free download and contains some exciting new features for your iPhone, iPod Touch, or iPad.  

The first of these is AirPlay support for videos stored in your Photos app.  This allows you to wirelessly stream the videos shot on your device to your TV using a Wi-Fi signal and Apple TV.  This upgrade also adds support for streaming audio and/or video from third-party apps, such as MLB At Bat (iPhone or iPad) and Pandora that have been AirPlay enabled.

Support has also been added for streaming media to your mobile device.  With iOS 4.3 you are able to stream your music, movies, TV shows, audiobooks, and podcasts from your Mac or PC.  Note that this feature requires a Wi-Fi network and iTunes 10.2.

Safari, the Web browsing application, has also been upgraded.  The new Nitro JavaScript engine allows your device to run JavaScript up to twice as fast as before.  JavaScript is a programming language that is commonly used for interactive features on Web pages and can consume a lot of processing power, so this upgrade should greatly improve your Web browsing experience.

The final majorly updated feature is Personal Hotspot for iPhone 4.  This allows you to use your iPhone 4 as a mobile Wi-Fi provider for any Wi-Fi-capable device.  Up to five devices can be connected to one iPhone through Wi-Fi as well as USB or Bluetooth.  Personal Hotspot requires a supporting hotspot tethering plan from your carrier and works with up to three devices over Wi-Fi, three devices over Bluetooth, and one device over USB.

To install iOS 4.3 on your iPhone, iPod Touch, or iPad simply connect to iTunes and follow the on-screen prompts.
