Can Apple permanantly block jailbreak on all future firmware?

Make no mistake: Jailbreaking plays a MAJOR role in keeping some iPhone-fans in the game. I don't think Apple have any real interest in stopping the jailbreak-community, but trying to make it look like they're making an effort sends a good signal to their devs, while keeping the JB-community under the pressure we enjoy so much 😉

You call me naive, and then disregard piracy? THAT my friend is naive.

Naive is thinking everyone jailbreaks for one reason. Do you do it? If not, then how do you know why people jailbreak? If you do then you must pirate? 😱

Also, google iPhone and see what comes up. Don't think Apple needs any more publicity. They've already got leaks everywhere all over the news, why would they need jailbreaking to boost their ratings?

Because jailbreaking makes the iphone 100 times better. Check out the new features of 4.0... Folders, multitasking... Wow, sound familiar?

Damn straight! That is what I meant by 'its a game' if you hadn't realised.

no, its been just as easy as always. calm down.

I'm simply trying to demonstrate that it's in Apple's best interest to leave the jailbreak open and I think if they really wanted to patch it they would have already.

They have. Several times in fact.

There never is a guarantee that another exploit exists. But since no software is without error, I'd always bet there is. But it might be very hard to discover. (see PS3, which took years to crack open)

What about unlocking?? I think that that is much more important. I could easily live without my iPhone jailbroken, but i couldn't have it locked (i know that you have to be JB'd to be UL'd).

One way of rephrasing your question is "Can Apple write firmware that is 100% free of any bugs that could allow running of arbitrary code?", and the answer is "No."

While I believe Apple to be the among the best software companies, for the past 50 or so years, I don't think anyone has ever written an entirely bug-free piece of software, let alone one as complex as iPhone OS. What has happened so far, and what will continue to happen, is the cat and mouse game: With every new iPhone OS, Apple patches previous bugs allowing jailbreaks, and hackers find new ones.

Laws of programming:
1. A program can always be made simpler.
2. There's always one more bug.
Therefore by extension, any program can be made into a one line bug.
