The new ios 6.1.3 Untethered Jailbreak was finally released today by the new hacking team called silv3rwind. They claim their jailbreak for ios 6.1.3 is fully working and they just released it today on 19th March 2013.
The new ios 6.1.3 patched the older jailbreak tool evad3rs which was used to jailbreak the older 6.1.2 and 6.1.1 apple idevices.
6.1.3 beta 2 update and found that it patches at least one of the five bugs the jailbreak exploits, namely a flaw in the operating system’s time zone settings. The beta update likely signals the end of using evasi0n to hack new or updated devices after the update is released to users, says Wang, who says he’s still testing the patch to see which other vulnerabilities exploited by the jailbreak might no longer exist in the new operating system.
Also the new iOS 6.1.3 patched the security bug which caused some users to get pass the security code using a bug in the apple idevice system.
