Apple's strikes again, sending jailbreakers on their heels

Apple plays what its CEO Steve Jobs once likened to a game of "cat and mouse" with iPhone unlockers and jailbreakers.  Jailbreakers, like the iPhone Dev Team, try to release the iPhone from being limited to the official iTunes app store and other firmware restrictions, while unlockers, such as George Hotz, use the jailbreaks and other techniques to unlock the phone, allowing it to run on any hardware-supported network.

Usually the unlockers/jailbreakers seize the day, but occasionally Apple will win a round.  Apple has tried many approaches -- everything from "bricking" unlocked iPhones to denying jailbroken iPhones access to the iTunes store -- to halt the spread of unlocking in the U.S. and force people to use AT&T, despite the hardware being capable of working on other carriers such as T-Mobile.

Now, Apple has managed to gain an upper hand over the persistent hackers according to iClarified, thanks to the release of a new bootrom, iBoot-359.3.2.  The phone firmware, which shipped on new iPhone 3GSs starting this week, closes previously used doors to exploits.

A user named "Mathieulh" first noticed the new bootrom and took a screenshot.  It was subsequently confirmed by Muscle Nerd of the iPhone Dev Team that the loss of the 24kpwn exploit would render the iPhone unjailbreakable for the time being.  This means that the unlocking fixes, such as the utility released by George Hotz, also won't work anymore as they rely on jailbreaking as a preliminary step.

For users wishing to jailbreak, iPhone jailbreakers are hard at work trying to find alternative exploits that could be used to unlock the phone.  They suggest, in the meantime, that users purchase older stock of iPhones or buy refurbished units.

The iPhone 3GS was unlocked as soon as it was released, thanks to unlockers with iPhone Developer connections.  George Hotz used the iPhone Dev Team's exploit, along with his own methods, to publish a route to jailbreaking the phone just weeks later.

It is only a matter of time, but exactly how much time depends on whether the iPhone Dev Team have other as yet unused exploits they can use against this new bootrom (if so, they could potentially immediately release a new fix) and just how soon they would want to make such an exploit public (it is best to always keep something else in reserve for after Apple fix whatever you have been holding back, as if you play all your remaining cards, it could be quickly stopped and you are left with no way of responding until something new is discovered).

This new bootrom will no doubt be worked around one way or another, but it may take a little while before the exploit is made public as there is no compelling reason to do so (wide availability of exploitable 3Gs models already). When it comes to this sort of exploit, it is better for the general public if they are not made known for quite a while so as to avoid Apple blocking it on new models sold sooner rather than much later.
