So you know that JailbreakMe site that let’s you jailbreak your iOS device? Well, Apple published an iPhone and iPad update today to plug that hole, and right after, iPhone hacker “comex” published the source code of the JailbreakMe site. Why is this relevant? Well, now any would-be evildoer has access to that exploit and can thusly infect any pre-iOS 4.0.2 device using the same exploit. So you have two options here if you want to stay safe. You can update to 4.0.2, or if you want to stay jailbroken, download the PDF Warning tool. One interesting thing in all this is that if you are running the original iPhone or iPod touch, Apple doesn’t have a fix for you. So you are essentially stuck with a vulnerable device unless you jailbreak it. How’s that for backwards?

Following up on their promise to quickly plug the gaping hole in MobileSafari that allowed a PDF exploit to jailbreak your iPhone using the JailbreakMe website, Apple has just released iOS 4.0.2 for the iPhone, and 3.2.2 for the iPad. There don’t seem to be any other changes other than plugging that hole, and remember, if you are already jailbroken and want to stay that way, hold off on updating. To anyone else, go for it—the update awaits.
