iOS 4.3 Review - iPhone/iPod/iPad/AppleTV

Updating is easy.
Just connect your device to your Mac or PC and follow the onscreen instructions in iTunes.

The world's most advanced mobile operating system keeps getting better. Download the free iOS 4.3 Software Update and get new features that let you do even more with your iPhone, iPad, and iPod touch. The software update is free. It's easy. And you can download it right now.

AirPlay Enhancements
More ways to AirPlay.
Get even more play out of AirPlay — the wireless technology that lets you stream content from your iPhone, iPad, or iPod touch to your HDTV via Apple TV.1 In addition to music, movies, and photos, AirPlay now streams video from your Photos app. So you can shoot a home video and instantly share it with everyone in the room. Even AirPlay-enabled apps and websites get the big-screen treatment with iOS 4.3. And if your photos are the feature presentation, you can play a slideshow with all the stunning themes available on Apple TV.

Safari Performance
Surf at the speed of fast.
As you surf the web, your fingers will love the responsiveness of the new Nitro JavaScript engine powering Safari. It runs JavaScript up to twice as fast as in iOS 4.2.2 Which means you get more speed behind each page load. And sites with lots of interactive features can appear on your screen even faster.

iTunes Home Sharing
Share over the air.
Now you can play your entire iTunes library from anywhere in the house. If it's on your Mac or PC, you can play it on your iPhone, iPad, or iPod touch over a shared Wi-Fi network.3 And not just music. Watch a movie or TV show. Play a podcast. Or listen to an audiobook. On whichever device you want — without having to download or sync.

iPad Side Switch
Switch it up.
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.
Silent or screen rotation lock

Personal Hotspot for iPhone 4
Get online in more places.
On the road, in an airport, at the park — now you can bring Wi-Fi with you wherever you go. Download iOS 4.3 on your iPhone 4, and the next time you find yourself without access to Wi-Fi but in 3G territory, enable Personal Hotspot and share your cellular data connection with your Mac, PC, iPad, or other Wi-Fi-capable device. You can share your connection with up to five devices at once over Wi-Fi, Bluetooth, and USB — with up to three of those connections using Wi-Fi.4 Every connection is password protected and secure. And it's power friendly, too. iPhone detects when your Personal Hotspot is no longer in use and turns it off to save battery life.
