writes "Apple Insider is reporting on a browser-based 'jailbreak' for iPhone 4. Hackers on Sunday released the first "jailbreak" for the iPhone 4, a browser-based exploit that allows users to run unauthorized code. Unlike previous jailbreaks, which required users to run software on their Mac or PC and tether their iPhone to their computer, the latest hack is done entirely within the Safari browser. Users simply visit the URL to begin the process, which modifies the iOS mobile operating system found on the iPhone, iPod touch and iPad. Some users have reported that the modification results in broken MMS and FaceTime functionality. This jailbreak does not work on iPads running iOS 3.2.1.
The ability to modify iOS simply by visiting a website leaves these iDevices vulnerable to all sorts of malicious possibilities. I'd bet the ranch that Apple isn't the only one analyzing the website in order to diagnose this major security hole ... so are those with more nefarious intentions."Link to Original Source
