Apple releases iOS 4.3

Apple has just released iOS 4.3 for all of the supported iDevices. The latest firmware brings a number of stability improvements, battery enhancements, security patches and new features, including the much anticipated hotspot feature.

The new hotspot features allows up to three devices to connect through USB, Bluetooth or WiFi. Users can easily share their 3G connection with other devices with any WiFi-enabled device. The new hotspot feature is only available on the iPhone 4.

iOS 4.3 also comes with a number of Safari improvements, including an updated JavaScript engine, which helps render pages a lot quicker. The new Nitro JavaScript engine makes rendering some pages up to 2x faster than iOS 4.2. iOS 4.3 also comes with a side switch toggle, enabling you to mute or lock the rotation of the device, so you can stay in portrait mode while in landscape mode.

iTunes home sharing also received a big update, allowing you to play your entire library from anywhere in your home. The updated home sharing enables you to stream music or video to your iPhone, iPod touch and iPad. In addition to iTunes home sharing, comes a big AirPlay enhancement. The wireless feature allows you to share your multimedia from your iDevice to your HDTV with Apple TV.

The iPhone 3G isn't supported in the latest update, as all the new features added to iOS 4.3 do not support the iPhone 3G hardware. The latest update for the iPhone 3G is iOS 4.2.1, which was released on November 22, 2010, possibly the last update the device will ever receive.

iOS 4.3 is only available for the following devices:

  • iPhone 3GS
  • iPhone 4
  • iPod touch 3rd generation
  • iPod touch 4th generation
  • iPad (first and second gen)

Is anyone else here having a Battery Drain Issue with IOS 4.3? I have an Apple IPhone 3GS and have been having a nasty Battery Drain Issue ever since I installed IOS 4.3 Beta 3 (I am in the Apple Developer Program)!

Since my 3g is no longer supported, I'll probably jailbreak it and get most of the items that Apple wouldn't give me.

Hmm I just updated my iphone4, but I don't have the hotspot feature in my settings at all. Anyone else have this happen?

Figured it out. Apparently I'm a little slow..

The Personal Hotspot feature is pretty sweet! Waiting for this forever, and thank goodness all the Canadian carriers enabled the feature for free! Just got over 6 Mbps down and 4 Mbps up with Personal Hotspot on the iPhone 4. Awesome!

Incidentally, is there a way to change the name of the Personal Hotspot to something other than Owner's iPhone? ... the apostrophe doesn't show up right in Windows 7 ... the SSID shows up as Owner’s iPhone ... even though other networks with an apostrophe in their name don't replace the ' with ’

That looks like you log in with some crap-default account on your computer called "Owner", and went with the crap-default iPhone name of "username's iPhone" (which made it "Owner's iPhone").
Have you tried changing your iPhone's name??

I'm substituting 'Owner' instead of my first name ... the problem is the display of the apostrophe. Two Windows 7 devices show the network name as "MyFirstName’s iPhone"

OK figured it out. Just had to type in the name again in iTunes ... for some reason it had the backwards apostrophe ` instead of the regular one ' between my name and the apostrophe s.

My 3GS froze for a couple of times... several hard resets did the job.
Enjoying 4.3 although I not know what the benefits and speed improvements are...

If iunderstand correctly, this update is not for the verizon Iphone4?

Pretty sure the verizon iPhone already comes with 4.3...

Where does it say that? Unless Verizon iPhone 4's were shipped with 4.3 or something... idk.

Jonzy said,

No, it isn't. The Verizon iPhone came with 4.2.6. 4.2.6 contains a number of 4.3 features, but not all. Apple hasn't announced their plans for the Verizon iPhone. The worst case for those users are: No further updates to their phones until iOS 5. But we'll see.

instead of waiting you could be finding exploits and helping the jb community

I would if i would know how to.

Navan said,
does this mean iOS 5 won't be for iPod Touch 2g?

Unfortunately no more iPod Touch 2G updates. I own one too. Iphone 3g is dropped too; 3gs is the next one to be dropped at some iOS 5.x release, sure lol

I can say what I want as long as it follows the rules so go worry about yourself. If you want to start something, find someone else.

Get used to it. The anti-Apple trolls around here love putting words in the mouth of Apple (and Apple fans).

No, they don't. As we can see now after the announcement.

People like you are tiresome.

You keep bringing this "my rooted Android phone does..." argument to every piece of Apple related news. If you want to compare Androids to Apples, at least have the decency to point out features and experiences of a non-hacked OS. When you make it sound like free WiFi hotspots are an actual feature of a non-hacked Android handset be prepared for someone to call you on it as being not-true (at least not-true for all service providers).

Ahhhh good to know. I read the first post about an Android always having a free wi-fi hotspot and thought that it came with the device. (Although I've never done any real research on the Android but it's good to know)

iPad only.

Don't think so. As I mentioned on an earlier post, I have a VZW iPhone with 4.2.6 and already have the rotation lock. I have to believe 4.3 is just bringing it to the masses so to speak.

sarcasm: Thanks for the long support for the iPod Touch 2g

They supported it for 2 1/2 years, try finding that long of support for a similar device from most other companies.

Indeed, that's not bad, tbh.

Yup, also agreed with Kirkburn, I thought that my little iPod was going to be garbage after iOS 3, but for my surprise it got up to iOS 4! (Something that the first iPhones/iPods didn't have

Its still there, just have to activate it using XCode.

So it's not there by default? We have to hack it? that's sad

It was always stated in the sdk release notes that it would not be available for customers. It was for developer feedback only.

Downloading right now... especially interested in the hotspot function and the JS improvements in Safari.

I don't get how that's considered new? I have a VZW iPhone with 4.2.6 and have always had the hotspot and the rotation lock (for the whole month I've had it). Not really new to 4.3 unless they're only talking about AT&T users.

And users in other countries.. So easy to forget...

I'd just like to flag up once again that hotspots worked fine on 3GS during the Betas and was removed from the final for no reason -.-

OK, we have already heard it the first 1000 times the people have mentioned it. And I really doubt that it was "for no reason". Just not a reason that you are privy to.

Did you try the final to make sure it was taken out?

Used it a lot of a friends 3GS during the Beta, worked perfectly fine.

Considering all of the issues that Apple has had with iOS 4 on the 3GS, many of which seem to affect devices randomly, I can easily believe that although it worked fine for you, it might not have worked fine for some other beta testers, which might be why Apple removed it.

I think it just removed to force us to buy an iPhone 4.

Duh... same thing with MMS for the first iPhone lol

0sm3l said,

I'm thinking that one was because by the time MMS was enabled, AT&T was already allowing first gen iPhones to be used on prepaid plans, and they likely didn't want those users having MMS capabilities.

waiting for a jailbreak

There already is one, but it is tethered. Waiting on an untethered jailbreak would be more accurate.

Probably shouldnt be jbing if you don't know that one. Tethered means you lose jb if you restart phone.

...if you restart your phone w/o it connected to your computer.

ccoltmanm said,

I guess you shouldn't be jailbreaking then? Because what you said is wrong. "Tethered" means you cannot reboot your device without connecting it to a computer to re-jailbreak, since it won't get past the "connect to iTunes" screen.

What you described is "semi-tethered". It allows you to reboot, but upon rebooting, the jailbreak is lost. Re-jailbreaking restores all previous functionality, though.

Please don't be arrogant next time, just try to be helpful. You're only hurting the community otherwise.

Only 3 devices for the hot spot?. Why the limitation

Actually, it is 3 for Wifi, plus one each for USB and Bluetooth. Most mobile hotspot devices (and phones with the feature) have some limit on the number of connected devices. And really, considering the bandwidth of 3G, are you really going to be hooking up 5+ devices to the connection?? If so, you are going to have a very slow connection on each device.

roadwarrior said,

If so, you are going to have a very slow connection on each device.

Depends on what you are doing with each device. Just normal email/basic web browsing wouldnt be so bad with 5+ devices. Now if you were streaming video, then ya...slow as hell.

roadwarrior said,

The description that came up before I downloaded the update said upto 3 wifi, 3 bluetooth and 1 USB. And a maximum of 5 from that pool in any combination at a given point in time.

OK, thanks for the correction. I was wrong about bluetooth, but right about the overall total.

Ruddy Apple with their limitation it kind of sux a little us 2nd Generation user don't get an update.

And tethering requires CPU resources, A4 processor may not be capable for 5+ devices plus the device's OS
