iOS beta 6.1.3 2 was released last week by Apple, and planetbeing said absolutely nothing about the possibility of exploiting the new version of iOS using evasi0n. His silence had a purpose, that of publicity, and in one intervened granted Forbes, he stated that iOS beta 6.1.3 2 fix at least one of the 5 bugs used in evasi0n, more precisely the one that exploits the timezone system. Practically, evasi0n will no longer work when iOS 6.1.3 will be officially released, even if Apple blocks only one bug.
Wang tells me that he's analyzed the 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. "If one of the vulnerabilities doesn't work, evasion doesn't work," he says. "We could replace that part with a different vulnerability, but [Apple] will probably fix most if not all of the bugs we've used when 0 comes out."
I didn't expect Apple to block the jailbreak solution for so quickly iOS 6 and you can be sure that until the official launch of iOS 7 we will not see another jailbreak solution, especially since the new operating system could reach users as early as June.
UPDATED: According to i0n1c, iOS 6.1.3 beta 2 blocks a second exploit used in this jailbreak solution. Although planetbeing has stated that Evad3rs still have jailbreak exploits through which they can exploit iOS 6, they will not do so, preferring to keep those exploits for iOS 7, as the I already told you in this article.
So iOS 6.1.3 beta 2 also fixes the overlapping segment attack against dyld used in evasi0n
