iOS 4.3.4 Prevents Hacking and Jailbreaking

Mightee writes "Apple has released a software update to iOS, version 4.3.4, for the iPhone 4, 3GS, iPad 2, 1, and iPod Touch. The main objective of this version is to prevent the hacking in Apple iOS devices which occurs through malicious PDF files. Another objective is to prevent the jailbreaking which occurs as a consequence of the previous effect. In previous versions, the iOS device is easily vulnerable to attacks. It happens because of mishandling of fonts embedded in the PDF file. Sometimes a downloaded PDF may be malicious, and there is a possibility that the file could inject malware into the iOS device, which gives a chance for the hackers to access the hardware of the iOS device."

      iphone does everything i want in a phone and doesn't feel like it is made of cheese like all the samsung/htc devices i have encountered. so, as far as i'm concerned, apple deserve my money.

      Sorry mate but the tethering fee is NOT an iOS issue. I can tether my iPhone to any of my devices and not pay a fee and I haven't even jailbroken it and refuse to to do because there is no legitimate need to. The tethering fee seems to be an American and Canadian thing not a rest of world thing.

      Don't blame Apple blame your crappy cell companies.

      I can tether my iPhone (via Bluetooth or USB to a single device, or via Wifi to up to 5 devices), without a fee. Your ~telephone company~ may charge you a fee for doing it. My carrier doesn't charge for it (actually I don't think any major carriers here do - some of them used to, but people bitched about it too much and they got rid of the fees). But it has nothing to do with the phone itself. Complain about your carrier, not the phone or OS.

      There are legitimate arguments to be made against Apple's/iOS's restrictions. But that is not one of them. The rest of your points are very valid but it hurts your argument somewhat to lead off with a falsehood - makes you sound like a blind Apple-hater that doesn't care about the actual facts.

    Its as if this update solved all problems and will solve all problems in the future.

    "iOS 4.3.4 solves known pdf exploits"

    Would have made sense.

    None of this "Prevents Hacking and Jailbreaking" nonsense.

      Better description would be "iOS 4.3.4 fixes known PDF security flaw".

      This is a good thing. If you can use the flaw to root your phone, then so could someone else. But then that would be a less sensationalist article.

      You know what is funny? The person who wrote the jailbreak (comex) also put a patch for the PDF flaw in the jailbroken debian APT system for the phone.

      The funny part is since iPhone 3G's and earlier iPod touches don't get firmware updates anymore, being jailbroken is the ONLY way to be free of this flaw in those earlier devices.

  4. Backup your SHSH files - NOW by DanTheManMS · · Score: 5, Insightful

    Anyone with an iDevice reading this, please go backup your 4.3.3 SHSH file right now. Even if you don't think you'll ever jailbreak, please do it as an insurance measure. It's as simple as downloading a program (TinyUmbrella), connecting your phone to the computer, and clicking a button. Behind the scenes it's saving Apple's magic "approval" that allows you to restore your device to the fully-hacked 4.3.3 firmware. In the next few days, Apple is likely to stop signing restore requests for anything except 4.3.4.

    It's not that I expect most people to actively *want* to downgrade their firmware in the future. I just like having the *option* to do so. For instance, right now I could restore my iPhone to iOS version 3.1.3 if I wanted to, even though Apple stopped allowing restores to that version years ago.

    "Sure, the boys in Steve's lab can make it hack-proof. But that don't mean we ain't gonna hack it.". All we need now is someone to come out with a jailbreak that depends on the success of a plumbing minigame and we're in business!

    Seriously why don't folks just accept if you want Steve's toys you have to play with them Steve's way? If you want freedom to do what you want with YOUR device you do NOT want an Apple iShiny, what you want is this little thing called an Android. Hell even the WinPhone is more open last I checked, as they made it butt simple to load third party apps.

    Not to say old Steve don't make good gear, hell the man is famous for cutting out the bullshit and making things simple that "just work". But surely by now everyone has to know Steve has always been a control freak, going back to that Apple that would overheat because Steve hated the sound of fans.

    Apple will ALWAYS be the most locked down walled garden approach, that is how Steve makes sure things are just the way he likes it, and as a side effect it'll make it so Apple doesn't have to worry about malware without actually hardening the OS, just make it so only pre-approved apps run and there you go. If that doesn't appeal to you? Get Android or WinPhone or WebOS devices, it isn't like there isn't plenty of choices out there.

    I just don't get why people would pay for the Apple markup only to turn right around and look for ways to break into the thing. it just seems like a lot of work when there are plenty of other choices. Vote with your wallets people, if design and simplicity matters? Buy Apple. If being able to control your device and do as you please matters to you? Get something else. Why is that so hard?

    You probably use 15 electronic devices a day which have microprocessors capable of running arbitrary code but which the manufacturer prevents you from easily running arbitrary code. Why is Apple the bad guy? They are not the first ones to ever make a locked down device.
