Apple released iOS 4.3 Wednesday, a couple of days before its expected release date of March 11, alongside the official launch of the iPad 2. The update includes many new features, like Personal Hotspot for iPhone, Home Sharing, iPad hardware switch function customization, improved AirPlay and better Safari performance.

We’ve covered the new features as discovered in the developer preview, and as announced officially by Apple at the iPad 2 event last week, but here’s a quick rundown of what you can look forward to when you get this update up and running on your iOS device:

  • Personal Hotspot. Share your iPhone’s data connection with other devices via Wi-Fi. Personal Hotspot can support up to five devices, but you may be limited to three depending on your carrier.
  • Home Sharing. Access your shared iTunes libraries from your iOS devices. Home Sharing used to be limited to Macs and the Apple TV, but now you can wirelessly stream music stored on your Macs on your iPhone or iPad using it, so long as the devices are on the same local Wi-Fi network.
  • Lock/Mute Switch for iPad. Change your hardware rotation lock switch into a mute switch in your iPad’s Settings. This is one users asked for, and it’s great to see it finally arrive.
  • AirPlay for Third-Party Apps. Now third-party apps have full access to the AirPlay API, letting them stream video to your television via Apple TV. This is great news for people with extensive local video libraries.
  • Improved Safari Performance. Mobile Safari runs much better using iOS 4.3, thanks in large part to improvements in how it handles JavaScript performance. We shared some impressive benchmarks that show just how much speed is improved just the other day.

  1. My update just failed, necessitating a full restore. Grrr! iPhone 4 on 4.2.1.

  2. No update for Verizon iPhone yet. I’ve been on the Check for Update button for about 20 minutes

    1. iOS 4.3 not supported on Verizon iPhone. Pretty stupid if you ask me.

  3. Oh, awesome. Now it won’t restore VERY UNHAPPY customer, Apple. What the heck am I going to use today????

  4. @Allister

    Plug the phone into your machine while holding down the home button. keep holding it down till your computer says something about recovery mode. Restore as normal from there.

    1. Thanks Daniel. It actually went into recovery mode by itself! And then refused to restore. After being without my phone all day I got home and looked up Apple’s advice which included trying a restore from another Mac. That did the trick after two attempts.

  5. I just updated to 4.3 and see no difference in Safari browsing speed. Hotspot is a nice tough though…

  6. This is also, finally, supposed to fix the problem that an iPhone or Pod touch no longer works in Volvo in-car audio systems. I can’t wait to test this after having to do for so long without a serious audio source!

  7. It also let’s you stop the volume buttons from changing ringer tone and alarm volume. If you listen to music you don’t have to readjust the ringer tone afterwards.

    1. That’s not a new feature. Well, not new in this update anyway.

  8. one of my friends he send me the iphone 4 from overseas but its not working not catching the network what to do??? does ios 4.3 fix my problem plz i need help

  9. iPhone 4 for verizon is not supported in the new update. So quit trying to update if you have verizon.

  10. The gestures they said wouldn’t be in it, are in it! swipe between apps, swipe up for multitask, pinch for home.

    1. The gestures are currently only available for developer testing – Apple hasn’t activated them across the whole system. Apparently they want to give developers time to compensate if their apps already use four or more touch points, which could be misinterpreted as one of the new system gestures.
