iOS 4.3 brings few new features to the iPhone, iPad and iPod!

iOS 4.3 doesn't bring nearly as many changes to the table as iOS 4.2 did last November. The release of iOS 4.2 was a watershed moment for the iPad, bringing features like multitasking and folders that made it a far more useful device than before. The iPhone got fewer new features in iOS 4.2, some of which have proven more useful than others; I use AirPlay almost every day to stream from my iPhone to my home theater system, but I used AirPrint once, then forgot about it. For the iPhone, iOS 4.3 brings even fewer marquee features to the device. These include:

AirPlay Enhancements: 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. 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: 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. 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: 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. 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.

Personal Hotspot for iPhone 4: 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. 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.
