iOS 4.3.1 coming within 2 weeks?

iOS 4.3 for iPhone, iPad walkthrough

Boy Genius Report, which has gotten good information on iPhone, iPad, and iPod touch software updates in the past, is hearing from their sources that iOS 4.3.1 will be pushed out sometime within the next week or two and will address:

  • Baseband updates for the 3GS and iPad (original)
  • Fixed memory hang that results in memory corruption when reading large files from USIM filesystem
  • Fixed problem with NTLM authentication in apps and on websites
  • Fixed issue with the Springboard and 3rd party apps not recgonizing the gyroscope on the iPad 2
  • Fixed iPad 2 jailbreak vulnerability

Hopefully it will also fix the lack of Nitro support in full-screen web clips. Anything else you're hoping gets the bug smasher love in iOS 4.3.1?

iOS 4.3.1 coming within 2 weeks?

47 Comments

True, Apple needs to fix apps crashing and battery drain on 4.3. iPad 1gen battery was better than my iPad2 but i think is a firmware issuse.

Yes, better battery time on the 3GS would be nice. It has gotten so bad since 4.2. My wife's 3GS only lasts a few hours in standby.

There's a duplicatable bug in Facetime, where it only displays an image of a previous Facetime session and stops sending images until you reboot the device.

ios 4.3 intruduced "PING" I found on the Apple Forums that this could be suspect for battery drainage. I turned off PING and found a great improvement to battery life.
Select "Settings" "General" "Restrictions" you will have to create a Passcode to turn PING off. Others have also suggested signing off from the Apple Store as well.

Did all of that including resetting network settings as well as doing a full-discharge-battery cycle. With the number of apps I have on both my iP4 and iPad, there's no way in heck I am going to do a reset to factory settings without a backup. The battery discharge on both my devices has been significant.
There was no mention of addressing this issue from the "leaks" (no pun intended) but we can only hope that a tweak here and there will improve the situation.

Lots of the apps, have issues, as well as home sharing. I think 4.3 was not ready for prime time.

4.2 was more stable and faster than 4.3.
4.3 on iPad is winding me up. Phone a bot better

Please fix the home button issue. Last night I pressed it about 20 times (no exaggeration) before it finally responded.

Do like I do - find a stable OS and stick with it. Apple talks about the instability of jailbroken apps and iPhones yet they can't even keep their stock OS bug-free. LOL! I'm a happy chappy on 4.2.1 jailbroken. :)

Spent 6 hours trying to downgrade to 4.2.1 on my iPhone and iPad because my battery was draining insanely fast on both devices, not to mention a lot of apps were crashing on 4.3. Hope the update fixes those.

Ever since updating to 4.3, my 3GS randomly reboots several times a day. Anyone else experiencing, and any idea if this will be addressed in 4.3.1? Genius bar had no idea on what issue was.

1) Fix the unlock slider. It's lousy.
2) Battery life is terrible now with 4.3 so please fix that!
3) Video files that mult-channel audio are no longer supported with 4.3 which has me horribly aggravated! I should be able to play multi-channel movies through my Apple TV and enjoy them in all of their surround sound glory. Fix that Apple!!!

is anyone else having clunky animation/transition issues after 4.3 update? iphone4/windows 7

I'm also having the same clunky animation issue (especially with the slider). I'm using 4.3 on a 32GB 3GS and so far I'm not all that happy with it.

The battery life is significantly lower on my iPhone 4 since upgrading to 4.3. I pray to the good Lord above that Apple fixes this with 4.3.1, because I'm tired of turning my 3G off just to make it through the day.

Please fix wifi. I almost need to be on top of the router for the i4 to pick up the signal... Not happy!

To bad this article did not invite positive feedbacks as well. Or ask readers to specified if their idevices were jail broken or not. I. Think those would be interesting numbers.

The only BIG issue i have with 4.3 is the audio output in my car via usb. Prior to updating to 4.3, hooking up my iPhone 4 to my head unit in my car via usb worked flawlessly. Since updating I get a crackling sound. I know for a fact it is not the speakers or the head unit since it sounds just fine through the Auxillary input with my iphone.
I read over on apple's website forums that others had this issue with other software updates as well. However, mine worked fine until this update.

As far as I know there is no good JB out yet for 4.3 so the people posting about problems and bugs are on pure iOS 4.3. From what I hear you are better off JB on 4.2.1.

Summary: My bet is on iOS-wide Nitro support for iOS 5, not before.
Details:
I'd be very surprised if the Nitro changes land in the 4.3.1 update. This comes down to a security issue. Nitro gets its performance boost via a JIT (Just In Time) compilation strategies for Javascript. That is, Nitro optimizes key code paths in a page's Javascript into native ARM code on the fly. This requires that the process (Safari) be allowed by the iOS kernel to write executable code to memory. This capability is turned off for userland memory pages by default to reduce exposure from attackers trying to inject malicious code into an App, e.g. via buffer overrun attack. It doesn't fix the overrun, but non-executable pages prevent the injected code from being run.
Safari as a separate process has apparently has writable, executable memory pages enabled to allow Nitro to run. But embedded browsers and full-screen web apps on the home page aren't considered so trustworthy. (Note: a home screen app link that opens in Safari does get Nitro's boost.)
Daring Fireball notes that this isn't likely to get resolved until Webkit 2 comes to iOS. One of its key features is to allow Javascript and plugins to run in a separate handler process, which presumably could be locked down and JIT-enabled. I.e. at that point no app depends on in-process Javascript execution and Apple could conceivably turn on Nitro for everything.
To reiterate, my bet is on this landing with iOS 5.

People have been complaining about battery draining since 2007 and the first iPhone, i think people need to accept the fact that an update is never coming (or just admit that they have a severe case of OCD)

iOS 4.3 Battery Drain: How To Fix Ithttp://www.gizmocrunch.com/apple/6009-ios-43-battery-life-drain

Fix batter life... Just reading the comments and my batter life went down 4% and I'm at home using wifi. Cmon apple ur lagging

Battery life is pretty good here. 3GS on 4.3. At 98% after reading all these posts and surfing the web in wifi for last 10 minutes.

Pocket-Lint reports that they have found the culprit behind the iOS 4.3 battery drain and by disabling it, battery life should be "restored to what they were before the latest update." It's the notification system in Ping, and here's how you can turn it off:
Go to Settings > General > Restrictions and select Enable Restrictions. You should see the Ping setting there whereby you can click on the switch to disable it. You will of course now no longer receive music recommendations but should help the iOS devices last a couple more hours.
