When JailbreakMe release the Cydia iPhone 4 jailbreak, which can be done directly through a webby, they exploited a PDF vulnerability in order to hack your iPhone 4’s iOS 4. Of kush, jailbreaking has always been a mean to hack your phone to bypass what Apple initially locked down in order to have access to more features.

Now, Comex only manage to jailbreak the iPhone 4 due to the existence of the PDF Font’s loophole. And since Comex can do it, surely many other ‘unethical’ hackers would be able to also penetrate the security of your iPhone 4 and mingle in it.

Thankfully for the rooted and those who never intended to root, Cupertino claims it has already patched the hole. “We’re aware of the reported issue, we have already developed a fix and it will be available to customers in an upcoming software update,” an Apple spokeswoman told CNET. I’m not sure exactly when it will arrive, and in what form. But surely it’ll be around very fast as this concern Apple’s reputation too. In the meantime, don’t simply open any PDFs if you don’t need to, and don’t do anything illegal or immoral (to those ‘unethical’ hackers), and hit up Comex’s hack ASAP if your heart’s still set on that shiny new unlock, before Apple manage to patch it. Yes jailbreaking might be legal, and you have the backing of the Library of Congress, but iPhone’s still Steve Jobs’s child product, so who knows what he’s thinking.
