Could potentially force hackers to start 'from scratch' on new app
iOS 6.1.3 beta 2 -- seeded to developers late last week -- wrecks the evasi0n jailbreak, one of the members of evad3rs tells Forbes. David Wang elaborates that it closes at least one of the five exploits evasi0n currently depends on, specifically a glitch in iOS' timezone settings. Wang says he is still testing v6.1.3, but notes that if "most" of the v6.1.2 exploits have been fixed, evad3rs will have to start "from scratch" on opening up the new firmware.
Apple regularly undoes jailbreaks with iOS updates. The exploits needed to run a jailbreak represent security vulnerabilities, which Apple is typically aggressive about closing. The company is likely also eager to deter people from installing unofficial apps, since they not only represent potential security issues in their own right but run the risk of reducing App Store sales.
