Apple Releases iOS 4.3 for iPad, iPhone and iPod Touch


Apple (s aapl) 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.

Notice any other changes? Let us know in the comments.

I just downloaded the update for my iPad and it gave me an error message (37) and now it won’t restore or even turn on!!! thanks a lot, Apple!!!


Hey! There is an other new thing. Go in photos and go on a picture (not video) and then press the little play dow screen. There is a diaporama with music… Maybe this is not a great thing but its still new. :)

I updated both my iPhone and IPad to 4.3 today and the updates went fine. I have not played with the personal hot spot, but I used the rotate lock immediately.


hi i just updated on a pc and my facebook and safari arent even opening!! it just crashes right when i try to open it


I installed in 3GS last night, b/c someone on facebook said available.
First the latest Safari and iTunes.
I notice nothing new in iPhone 3GS.
Every update to iOS, I hope for better battery efficiency, but NOT.
I’ll likely get the next hardware version (5?).

Hmmm, no hot-spot functionality for the 3GS unfortunately…


This update changed the text tones that were added in the previous update. They have the same text names and sounds, but they shortened the tone a lot so that it actually sounds like a text ringtone and not a regular ringtone. Very pleased to see them do this.


I just down loaded the new update also and dont see any difference, maybe it kicks in on Friday LOL.


Any idea on how to use the home sharing functionality on iPhone 3GS?
Can’t seem to find how to use it on my iPhone… it’s activated in iTunes, used it for my other mac/atv


Hi from Mexico, just tried updating my iPhone 4… error 1013… WTF?! I’ve never jailbreak it… anyone else has this problem? how do I get it to work now? please, HELP!


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


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.


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


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


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.

Simon White

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

Rob Hooft

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!

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



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.


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.


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


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


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


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