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)

ReplyOnly 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.
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.

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
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.

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.
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.

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.
Yep it's gone.

Duh... same thing with MMS for the first iPhone lol
Duh... same thing with MMS for the first iPhone lol
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.
Why not? MMS is premium content, extract more money from pre-paid users who pay for every bib and bob they send.
Yep it's gone.
Whooa, that was quick. I thought they were gonna do it Friday? Oh well, good news for those that are waiting!
Downloading right now... especially interested in the hotspot function and the JS improvements in Safari.
And users in other countries.. So easy to forget...
Increased battery life for my 3rd gen iPod Touch would be wonderful. Not holding my breath though.
when will be the untethered jailbreak to be release for 4.3?
At 2:43pm PST next Tuesday. /s

how did you know? btw,thanks for the info if it's accurate.
Please tell me the MultiTouch Navigation for the iPad was put back in
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.
hmmmmm - itunes says its going to take 4 hours to download.
High surge of requests, should die down in a couple of hours.
f*ckers

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

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
Is the side switch toggle just for the iPad or for all iOS devices?
iPad only.
iPad only.
Grrg why? Why not add to to all iOS devices and then we can chose.
iPad only.
Can someone please confirm the build number as "8F190" for iPhone 4.

Battery enhancements ?
Apple invented the hotspot feature, or so they will say.
Always had hotspot on my droids....unlimited devices to...oh, and free to use.

Oh, AND JB iPhones enjoy the same free hotspot luxuries as rooted Android phones. Get off it already....

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.
They never said that...

Get used to it. The anti-Apple trolls around here love putting words in the mouth of Apple (and Apple fans).
But yes, it's a strawman argument.

Just like MS fans...Android fans...and all other 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).

does this mean iOS 5 won't be for iPod Touch 2g?
If you didn't get this release that's it for your device.
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
Updating.
The update is not showing up for me.
Update is useless without proper jb/unlock
Forced to wait now 
instead of waiting you could be finding exploits and helping the jb community
I would if i would know how to.
If iunderstand correctly, this update is not for the verizon Iphone4?
Pretty sure the verizon iPhone already comes with 4.3...

4.2.6
Where does it say that? Unless Verizon iPhone 4's were shipped with 4.3 or something... idk.
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.
Any benchmarks on the Safari performance?
Apparently it's not available for Verizon iPhones yet. http://www.appleinsider.com/ar...or_cdma_verizon_iphone.html
damn no 3G.... sux.
how good is it?
XCode 4 Released!!!

Why is it I can never download these updates? I always get a network timeout error after it downloads...
Am I the only 1 having issues setting up exchange account after this update?
We need untethered jailbreak and unlock, quick! go!
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...
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.
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..
Alas, my 3G becomes a paper weight...
R.I.P iPhone 3G
well apple beat MS to the update!
So... MyWi is dead?
Not if your carrier decides to charge for personal hotspot.
this has nothing to do with MyWi. lol
Why U so slow apple servers ...
Since my 3g is no longer supported, I'll probably jailbreak it and get most of the items that Apple wouldn't give me.
The new way the vibrate goes off for when you have a text is annoying. the two bursts should be a little longer.
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)!
