    Same thing, just a security patch to prevent jailbreak.

    What about the "...improved memory handling.", better performance maybe?

    It's possible, but it seems that it's "improved" in the sense that it doesn't allow for some security issue to be present.

    Nah, it is a phrase they use for memory-related security issues. Probably a buffer overflow or something like that they fixed with bounds checking or slight code improvements. Nothing spectacular, I believe.

    Doesn't fix the auto-brightness lag. Wasn't really expecting it to though since it's only released to prevent jailbreaking.

    The update size is around 24MB. Quite large to just fix a single bug. My guess, they also fixed several other bugs. Hopefully...

    Could be one change that affected multiple things or a few changes related to the same things. 24 MB isn't exactly that much really.

    Honestly, I see no good reason why anyone should update to iOS 9.3.4. Need convincing? Read on.
    • "I don't jailbreak my device, and I feel this security update is important to me." Even if you don't jailbreak, I highly doubt you'd be affected by this security issue through normal use, as it requires a specific signed app to be installed. Only Apple (or you through side loading) can officially approve signed apps, and if you're a side loader, let's face it: you're in the minority, and you probably understand the general risks around it in the first place.
    • "I cannot stand all the alerts/notification icon in Settings." As we know, there are ways to remove these through Settings and installing specific device profiles. So you shouldn't be too concerned about this.
    • "I want to get on the latest iOS 9 version so my device is worth more when I resell it." I get it; an iOS device on iOS 7.1.2 is definitely worth more than one on iOS 7.0. That being said, I feel like staying on iOS 9.3.3 is better for resale value than going to iOS 9.3.4. And this is because iOS 9.3.4 ONLY fixes an exploit that lets the end user have exclusive fun with his/her phone.
    • "I just want to be on the latest version. Period." Well if that's the case, there's nothing I can do to stop you. Just understand that there's ultimately no benefit by updating other than the satisfaction of staying up to date.

    Did anyone else notice that WiFi is required to download the update even though it was only around 26MB?

    This happened with iOS 9.3.3 too. It was about 56MB and still required WiFi.

    I was under the impression that anything under 100MB could use cellular. I contacted Vodafone and they have confirmed that they have no control over this so it's something that is being fully set by Apple.

    I believe you need to enable the Mobile Data in this setting page.

    Is that not just for app updates? I've got it enabled on my personal iPhone and it's the same at the corporate ones I manage - still needs wifi.

    No, that limitation applies to App Store downloads only. System updates require Wi-Fi.

    Yup, both of you are right, just tested it out on my other iPhone. They must have a good reason to do so though it is a bit troublesome for us.

    The benefit is knowing a drive-by vulnerability was patched, maybe along with other items.

    There are those of us, like me, who want my digital lives to be as secure as possible and that includes installing security patches for operating systems, electronic devices and what ever else can be updated.

    If you want to stay on a particular release feel free, but I will always update.

    My guess is that the need rarely arrises. System updates tend to be energy-intensive and they are disruptive. Apple still treats mobile data as the kind of data that you likely only use while on the road and most people do not have unlimited or large data allowances, so they avoid data usage that the user sees no immediate benefit from. App updates happen concurrently with the download, so that benefits more from data usage.

    Is 9.3.4 same as 9.3.3 in terms of speed on 6S?

    I know you're just kidding, but it's a pain to adjust the brightness manually all the time.

    Safari still freezes on me every so often when I'm using it...I have AppleCare+ but they just end up recommending a full wipe and it comes back again.

    Totally agree with you. If we need to adjust it manually, then we are going backwards already. Actually, the manual button should be a thing of the past.
