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.
The speculations did turn out to be true as one of the members of the evad3rs group, David Wang aka @planetbeing, has confirmed to Forbes that iOS 6.1.3 beta 2 does patch one of the vulnerabilities that they exploited in their evasi0n tool. Wang told Forbes that Apple has patched at least one of the five bugs, namely the time zone settings bug.
Wang had earlier said that they have found enough bugs in iOS allowing them to build a new jailbreak from scratch. But, Wang indicated that he is still testing the latest beta version to check if other vulnerabilities have also been fixed. If it turns out that majority of the bugs, they found in the first place, have been fixed, evasi0n jailbreak may not be useful anymore. In such a scenario evad3rs will be starting from scratch to build a new jailbreak.
Just before a week iOS 6.1.2 was released by Apple but evad3rs were quick enough to release an updated version of evasi0n that would successfully jailbreak iDevices on 6.1.2.
