hypnosec (2231454) writes "Apple recently seeded iOS 6.1.3 beta 2 to developers and it seems the beta version patches at least one of the vulnerabilities used by evasi0n thereby rendering the jailbreak tool useless — the time zone settings vulnerability. Released on February 21, the iOS 6.1.3 beta 2 brings with it enhancements to Japan Maps as well as fixes the much hyped Lock Screen bug. It was speculated that Apple would also patch exploits that would break evasi0n as it has been over three weeks since the jailbreak tool has been launched and Apple has had enough time to study it. David Wang aka @planetbeing, has confirmed that iOS 6.1.3 beta 2 does patch one of the vulnerabilities that they exploited in their evasi0n tool."
