i thought jailbreaking was legal and your right to do so..... why then does apple keep issuing patches to break the jailbreakers....?


Because this particular method of jailbreaking uses a security loophole that could be used by a malicious website to hack your iPhone. Whether you agree with jailbreaking, it's a good thing that Apple is addressing security concerns like this.

Jailbreaking is accomplished by exploiting a vulnerability in the device. Apple patches these vulnerabilities like any responsible company should.

Because the exploit can also be used to inject non-jailbreak related code.

Apple is patching the legitimate security vulnerability that allowed the jailbreakme break to work. Which could be used by other for malicious purposes.

It's a good precaution for Apple to take. Luckily the jailbreak community has already released their own fix, which means those jailbroken can keep their jailbreak and sense of security.

Since the PDF exploit is usable for far more than just a jailbreak, it's a genuine security risk.

Don't get me wrong, I'm a jailbreaker myself, but even comex himself will tell you that these PDF exploits could easily be put to bad use if people chose to use them that way. Comex even wrote a fix for this vulnerability, and posted it on Cydia, so that after people had jailbroken their phones, they could close the vulnerability without waiting on Apple.

Jailbreaking IS legal, but that doesn't mean Apple has to like it. They're well within their rights to attempt to close the holes that allow it. The ruling more or less just gave users the right to attempt to jailbreak. It doesn't make vulnerabilities in the iOS code an inalienable right that Apple has to put in/leave in.

No. It closes a security hole that just so happens to also be used by the jailbreak.

It being legal doesn't mean Apple has to like it. They can make it more difficult for you, but they cant sue you. I'm no lawyer, but that's my interpretation.
