Web-based jailbreak relies on unpatched iOS PDF flaw
@ 2010/08/03A new Web-based jailbreak was released recently for iPhones and iPads running the latest versions of iOS. Users merely need to visit jailbreakme.com from an iPhone or iPad to automatically jailbreak the device, allowing them to install apps and hacks that have not been approved by Apple. However, the process relies on a vulnerability in Mobile Safari that could be likewise exploited by more nefarious hackers to access all the data on your device.
