It's been quite a while now, and iOS 6.x is still vunerable to the Evasi0n jailbreak. According to reports, the next version of iOS 6 — iOS 6.1.3 — is expected to change that, stamping out the exploits and potential security vulnerabilities used by Evasi0n. In the mean time, though, it's all gravy. In fact, Evasi0n was just updated today, which brings its version number up to 1.5.2
Evasion 1.5.2 is a very minor update that has to do with language localizations. More specifically, support has been added to include localizations for the native languages of the Evad3rs: French, German, and Chinese.
