Apple's iOS Updates Kill Only iPad 2 Jailbreak

The new update conveniently blocks the only route of jailbreaking to the iPad 2.
OS update also closes a significant security hole
Jailbreaking phones -- removing operating system makers' restrictions on things like OS themes and allowed programs -- is today

amendments to the
Digital Millennium Copyright Act
[PDF] (DMCA). But just because it's legal to jailbreak, doesn't mean Apple, Inc. (
) will allow it.
Apple argued unsuccessfully to the U.S. government that jailbreaking could allow
terrorists to turn their iPhones into digital weapons
, and could assist drug dealers. Apple refuses to give users an open path to jailbreaking their phones, so users are forced to discover exploits that allow unauthorized code to be run. This is very convenient for Apple as it can justify closing the jailbreak route as a "security fix".
Thus is the case with iOS 4.3.4. The updates' only real action is to fix the mishandling of fonts in PDF files, which previously allowed for jailbreaking -- or malicious code execution.
Users can find the update here, for various devices:
iPhone 4 (GSM)
iPad 2 WiFi
iPad 2 GSM
iPad 2 CDMA
iPod touch 3G
iPod touch 4G
The update is significant as it cripples JailbreakMe 3.0, currently
the only way to jailbreak
Apple's new iPad 2 tablet. Jailbreaks are generally divided into boot-related jailbreaks and injection jailbreaks. Thus far no boot-level jailbreaks work on the iPad 2, due to its new A5 dual-core CPU. And the only injection-based jailbreaks currently in action relied on the PDF exploit.
The original iPad and present iPhone lineup is still jailbreakable via boot-level jailbreaks, such as redsn0w, PwnageTool and sn0wbreeze. There's little Apple can do to prevent these jailbreak routes, much to chief executive Steven P. Jobs chagrin. Mr. Jobs has expressed a
strong dislike for jailbreakers
in past interviews.
While Apple can claim the recent update was to "protect" users, in reality it will only add additional safety to the most careless of users. After all, a program called "PDF Patcher 2" was widely available via the Cydia app store and other sources. The PDF Patcher 2 does pretty much the exact same thing as iOS 4.3.4, but does so
the user has jailbroken.
It is presumable that most users who are knowledgeable enough to jailbreak in the first place would properly protect their phones against malicious code by adding the patch post-jailbreak, especially since the
instructs the user to do so.
So it looks like Apple has won this round. One of its devices is yet again unjailbreakable -- at least for now.

RE: It's futile to try and stop jailbreakers

Personally, I don't think Apple is dead-set against jailbreaking in the sense that every time someone jailbreaks someone as Apple gets furious and swears. Afterall, to Apple, an iDevice sold is an iDevice sold. And jailbreaking for Apple is a small price to pay for Apple to have a group of more tech literate than average customers and in the case of jailbreak developers, a group of very talented programmers, interested in pushing the iOS platform. Apple's concern is probably that jailbreaking doesn't become mainstream or used by the majority of users since it'll affect Apple's ability to direct their vision of where the iOS platform should go and could create a support nightmare if people who don't really know what they're doing jailbreak and start installing every theme and kernel patch their friends or relatives recommend in order to spruce up their device. As such Apple puts up a negative public face on jailbreaking keep it in check, but as you say, aren't afraid to hire jailbreakers or seem to go to the lengths Sony does to prosecute them.
