    The cat-and-mouse game between Apple and a cadre of hackers continues, as Apple is reportedly now shipping iPhone 3GS units that are jailbreak-proof. Several hackers specializing in iPhone 3GS jailbreaks are saying that the well-known 24kpwn exploit is no longer viable, because Apple is now shipping iPhone 3GS models with a new bootrom that can resist the hacking technique, according to iClarified .

    If you think that last sentence sounded like a bunch of technical nonsense, you're not alone. So let's break this jailbreaking jargon down:

    Death of the Hackable Bootrom

    A bootrom is a computer chip used in mobile phones to check the device's software when you turn it on, and makes sure the device hasn't been tampered with. I'm not clear on what the iPhone bootrom can do if it detects a problem, but a Blackberry bootrom can shut down the device if a problem arises. To use the jailbreaking metaphor, think of the bootrom as the prison guard who checks that all the inmates are where they should be, before letting the prisoners go about their day.

    Hackers used to get by the bootrom using the 24kpwn exploit that would make the guard think nothing was wrong, and everything was running normally within the iPrison. Before the iPhone 3GS came out, some hackers were worried the 24kpwn exploit wouldn't work. Fortunately for these computer rogues, Apple was not able to change the bootrom within its supply chain before the 3GS was launched.

    But all that may have changed, since iPhone 3GS devices reportedly began shipping last week with an updated bootrom. Nicknamed iBoot-359.3.2, it is believed the new chip is not susceptible to the 24kpwn hack. Basically, the iPhone 3GS now has a smarter prison guard.

    So what does this mean?

    Without a hackable bootrom, the new iPhone 3GS is not jailbreakable, which means that you cannot use software on the device that is not Apple approved.

    Another term thrown around a lot is 'unlocking' your device. An unlocked phone can run the device on any compatible cellular network , instead of whatever network the phone was originally tied to. The hack for unlocking the iPhone requires modifications to the baseband, which is the system responsible for phone calls and Internet access.

    I'm no hacker, so I can't tell you definitively if the new bootrom means the iPhone 3GS is impossible to unlock as well as jailbreak; however, an unlock is dependent on some operations that happen when your device starts up so my assumption would be that new iPhone 3GS phones are resistant to unlocking as well.

    So is this the end of jailbreaking and unlocking the iPhone? Probably not, those iPhone hackers are a pretty smart and crafty bunch. But the clock is ticking. Let's see how long it takes for them to come up with a solution to Apple's latest roadblock.

    This is a good news for developers (me), bad news for those who like to do things that are only able with a jailbreak.

    This is kind of old news. The new boot ROM is still jailbreakable. Only hitch is, any time the device is powered down it has to be tethered to a computer to boot back up.

    I'm willing to give the Dev Team a fighting chance in finding another exploit to use.

    Unlocking is dependent on the modem firmware. Anything after 3.0's has not been unlocked. Unlocked iPhones are able to update to newer firmwares by using modified IPSW's that preserve the older baseband and update everything else.

    The 2nd ge. iPod Touch had the same problem. For about 2 weeks.

    I wouldn't worry too much about it.

    The only thing that's news here is that there are still people who believe that hackers will give up or won't be able to find a way. While changes by manufacturers can slow hacking down for a bit, the reality is that it just presents the next big challenge that these guys crave. They all want to be the one who breaks the "unbreakable" code. Apple & others have a limited amount of time & resources to put towards developing their security. It simply cannot compete with the near limitless resource time from brilliant minds around the world who are looking for a challenge.

    In the end, when you put a corporate coding team up against the general hacking community, I'll always put my money on the thousands upon thousands of pizza & Mt. Dew fueled geeks.

    How does the act of jailbreaking affect you as a developer?

    Answer: it doesn't.

    What does affect you is people who use jailbreaking to take it one stage further and install cracked apps. Not eveyone who jailbreaks does this. I don't. I buy apps from the app store if I think they look good enough (this brings me onto another issue that I don't like, in that if the app looks good but is then crap, I've lost my money, but that's not for this thread)

    If you are that bothered about jailbreakers stealing, put a paid for version on Cydia, you might see an increase on revenue

    Statistically it does.

    Estimated at 38% * (7.4% - 0.43%) of 4 million broken devices according to pinchmedia analytics. I would guess more like 1/10th of that. But even that tiny percentage can add up to a big number for a popular app. Especially if a developer has per user server or support costs to pay.

    The thing is that there's a very significant population of those jailbreaking that are doing it for reasons other than piracy. I can't count the number of times I've heard people outlining how they were interested in jailbreaking for the sole purpose of gaining access to features that Apple simply wouldn't allow (background apps, teathering, UI changes, Slingbox over 3G, etc.)

    Oh and plus. If hackers can gain access to a device, apps / games will be pirated for the device. As long as their is a jailbreak, there will be pirates. That cant be stopped.

    Of course. But if Apple makes it easy for one portion of the population, they also make it easy for the other portion (and potentially for malware and botnet distributors as well).

    Don't waste your time with that free app store battery percentage app. Download MyBattery from Cydia. Free and perfectly accurate.

    Ouch. I guess that allows you to jailbreak it, but it also defeats the purpose of a phone.

    No, my arguement was for jailbreaking. Jailbreaking doesn't mean that the jailbreaker is going to download the app store and install an many pirated apps as possible. It is a method used to allow for pirated apps. Pinchmedia's stats said that about 38% of the 4 million jailbroken devices that phoned home had the app installed through pirating it.

    I have got the phone home "feature" turned off through privacy, something that non-jailbroken devices can't benefit from. I don't have this turned on because I pirate apps, but because I don't like people getting info about me when I don't know what the info is, why they need it and what they are going to do with it.

    Piracy is now a part of life. People pirate everything and always will. Apple will close the door on it, not noticing that the pirates are already going in through the window

    With a + there will always be a -.

    With people doing there best to prevent hacks and exploits, there will be those doing their best to crack it.

    It's where a persons own personal morals and ethics kick in when they're at a decision to 'hack' something ;).

    lol

    lol you dont know much about it

    well the 24 k pwn was the 2nd hacked bootrom. second all device pre octer 09 can still be jailbroken on the current firmware. third you can jailbreak the new devices via thethered jailbreak so you just have to plug it into the computer every time you boot.

    fourth chronic dev already found and exploit so the unterthered version is on its way.

    me i now how jailbreaking is performed and who does it.

    lol

    This same game was played between Sony and hackers with the Playstation protable! Lol I remember back in '05, '06 I was very much involved in much of that. I actually did develop a few applications for use on PSP's with custom firmware not much though. The same thing is going on with Apple and hackers, from my experience it can't be stopped. I swear to God every few months Sony would introduce a new update with new features to try and counter tempted consumers JUST LIKE APPLE IS DOING NOW or come out with a new update that was supposidly "uncrackable" but you see there's some really smart people out there countering it, in fact I wouldn't be surprised if many PSP's hacker migrated to the iphone/ipod touch. There intelligence could be of much use. We will see how long it takes before they crack it. I remember the PSP's version of 3.0...a few months laters hacker cracked it. Just wait guys.
