Jobs confirms iPhone app blacklist feature

Straight from the horse's mouth: Apple's iPhones do indeed have the capability to check for, and potentially defang, software that Apple deems unfit for the iPhone.

Apple CEO Steve Jobs confirmed the existence of the so-called "kill switch" capability, following last week's ruckus over early reports of just such a function. The word from Jobs was tucked at the bottom of a story in The Wall Street Journal about Apple's hot-as-a-pistol first month of sales at its App Store.

The intent behind the capability is high-minded, Jobs said. Apple would need it in case a malicious program inadvertently were to be distributed to iPhones via the App Store.

"Hopefully, we never have to pull that lever," Jobs said, "but we would be irresponsible not to have a lever like that to pull."

On Friday, John Gruber of Daring Fireball spoke with an "informed source" at Apple who confirmed the presence of a URL inside the iPhone's Core Location API that downloads a blacklist of applications designated as malicious. The URL had been discovered earlier in the week by independent iPhone developer and author Jonathan Zdiarski.

If the reason is for security than I am surprised that Jobs doesn't know that blacklists are weak security.

Of course it it is to control what people who bought this overpriced, underfeatured POS do with it.

Let me guess: "The Decider." You're doing a parody of how W would answer, right? If so, good job.

You are aware that there are phones that cost a lot more than the iPhone right? Or do you just think you're being original by refusing to "follow the crowd" and get one?

I find it odd you'd waste your time commenting on a product you don't even own.

How long before some hacker is able to blacklist itunes on the iphone? I'm guessing 3 months.

"this overpriced, underfeatured POS" Can you explain? Please compare with similar offerings from Nokia, SonyEricsson, Samsung, LG, etc. As far as I know, they cost way more thath the iPhone. So what gives?

I agree, I went from CNET article to CNET article until I quit looking for it ("Experts say...")

They opened the iTunes store because a lot of people were doing it anyways, why stop now? people could go back, although I understand them removing illegal applications.

Blacklisting is up to Apple's choice. They decide what on your phone, not you. If an application is no longer listed in the Apps store because the developer fails to pay their yearly fee, Apple can remvoe the app from the Apps store *and* your phone and you have no right to say anything about it. Read the EULA, seriously. You didn't buy those applications, you are only renting them essentially.


Jailbroken apps from Cydia or Installer are immune... for the moment, but Apple can easily choose to disable that remotely as well if they so choose to do so.


It's just a continuation of cat and mouse for profit and control. Nothing new here.

Do you own an iPhone? That's what I thought.
Troll.

I'll second the troll comment: Dan is a MSFT employee/contractor, and I'm guessing (probably very correctly) that he/she/it doesn't own an iPhone.
by Vegaman_Dan August 11, 2008 9:00 PM PDT
iPhone? No. I have a Touch... which I have stated several times.


Pengunisto's comments can be treated with all the respect and honor that he deserves. Read his comments and make up your own mind based on that.

For something that rakes in over $1m each day, I doubt that this dramaganza made much of a dent. Here's the source article at the WSJ:

http://online.wsj.com/article/SB121842341491928977.html?mod=hpp_us_whats_news

Now for those with even half a clue, the blacklist critter sits in the library that has to do with location awareness, which means that certain apps will not be able to get info from your iPhone about where it is located. It does not stop the app from working otherwise.

Read for yourself on the how and why: http://daringfireball.net/2008/08/core_location_blacklist

If Apple really wanted to kill an app, they'd simply revoke the digital certificate... come to think of it, doesn't Vista have something requiring digital certificates? (cue MSFT fanboys scrambling to explain that one, and watch as they do so very clumsily... (evil grin)).

It's impressive that you are denying something that Apple themselves admitted exists. It makes me wonder exactly why you are going to such extremes to hide this information. What sort of financial gain do you get from this? It is definitely convenient and suspicious. Interesting indeed.
by gggg sssss August 11, 2008 4:50 PM PDT
wonder if they have a kill switch built into OSx as well. Besides teh code that prevents it from running on a non Mac bios.We know taht microsoft does with GU, but then we all know we should hate MS but love Apple. LOL

Vista has/requires digital certificates, no?

(also, WGA has been known to blast a legit computer or two...)
by Vegaman_Dan August 11, 2008 9:11 PM PDT
Penguinisto: Exactly what does Microsoft have to do with this? Does Microsoft have the ability to kill apps on Apple's iPhone? Or are you just spreading misinformation intentionally to slander another company simply because you have no life?


The evidence of your own posting doesn't really help your case here. You might try staying on the subject instead of trying to forward your agenda of hating all things Microsoft for the sake of your own ego.


Really. It's getting old. Try something new... like the truth.

Anyone feel like for every step Apples takes forward, it takes 2 backwards? I'm not saying that they don't do some cool stuff, but really, the way they tried to lock down where mp4s can be xferred to, the way they continue to try and lock down the iPhone ... it gets a little tiresome. It's a good thing there's plenty of alternatives. Btw, can the iPhone do videos yet?

Why not vet the apps _before_ they get delivered to the public? Do the due diligence up front and then, caveat emptor. Deciding not to carry in app in the store is one thing, killing something I already paid for is another.

The iPhone app kill switch makes sense. It is an innovative approach to protecting a platform in this age of criminal conspiracies to steal your personal information. As an iPhone user, I feel more comfortable about using the product. As for having paid for an app deemed malicious by Apple, that's more of a business issue, not a technological one. I think it's cool that Apple can kill an app that may be wreaking havoc out there. For more of my view on this, see my blog.
