A few hours ago @comex finally released his universal jailbreak tool for iPhone, iPod Touch and iPad called “JailbreakMe”. Unlike many previous jailbreak tools released in the past three years, this time you don’t need a computer to install Cydia on your device: jailbreakers are using the cloud now, and all you have to do is visit a website in Mobile Safari and wait for the exploit to “land” on your home screen.
Of course Apple isn’t happy about jailbreak. They never were. But this time - this time they have a pretty big issue on their hands. JailbreakMe seems to be based on a PDF vulnerability that is activable in Safari and, potentially, could lead to malicious software sent to users via emails and the browser.
