    Why are the iPhone 4s and 5 none jail-breakable, but the 3GS and 4 are, all of them running iOS6, what is the difference and what makes them unjail-breakable (at least for the moment)?

    Because apple doesn't want you to have freedom.

    The difference is that either you updated to iOS 6, or you bought the phone with iOS6 already installed. My iPhone 4s is running just fine, on iOS 5.1.1 jailbroken.

    Apple are getting better and better at eliminating exploits, though it does seem some progress is being made. iPhone 5 has apparently already been jailbroken, the jailbreak isn't quite ready for public use yet, though.

    I suspect things will only get trickier with every new model and iOS version.

    I'm a big jailbreak fan, and am not happy about this, either, at least not until Apple starts allowing apps with the same functionality to be published through their official store... might be just that reason I'm more open than I ever was to switching to Android, I dislike being smacked on the fingers for contemplating the use of something Apple has decided it doesn't like to see run on its phones. It's my device, let me do whatever the hell I want on it, and if that involves running some crazy linux derivative on it and running 50 different emulators, then so be it.

    My point is why iOS 6 can be jail-broken on iPhone 3GS and iPhone 4 and cannot be jail-broken on iPhone 4S and iPhone 5.

    The chips those older devices use has a big hole that hackers can easily crack with any iOS.

    I dont understand why Apple fights so hard to stop jailbreakers. I mean, some of the best ideas have come from the JB community (which Apple has ended up using in iOS releases).

    I think that's precisely because Apple feel like every good new idea should become incorporated into their own OS and improved on by them, as opposed to being a stand-alone feature which merely augments what is already there. They have a swallow and assimilate approach, while Google can stand a lot of features being independent to their OS, as long as they're compatible. Different philosophy, and I believe it's gotten to a stage now where Apple's way is starting to hamper rather than advance user experience.

    At the iPhone hacks section.
    The 3GS and iphone 4 have a bootrom exploit that gives them tethered JB's for life. That's a hardware exploit that cannot be patched with firmware updates by Apple.
    For the 4S and i5 currently such hole hasnt been discovered yet or there might not be one ever available on those.

    Apple wished to eliminate jailbreaking, by adding the popular features themselves. i.e. IOS 7, IOS 8...etc. IOS 6.1 makes jailbreaking even harder. By the time the iPhone 5 is jailbroken, Apple will have announced the iPhone 6. Maybe Apple will allow themes, widgets, improved multitasking...etc in IOS 7 further pushing jailbreaking to the point of why jailbreak.

    You have to realize that these exploits are holes in security that could be used by less than well-meaning people. While highly unlikely anyone could get a virus from it, there is still that posibility.

    Apple sees jail breaks as security holes and will plug these holes both reactively and proactively. Its just that simple.
