The 2nd upgrade of evasi0n, the jailbreak tool for iOS 6, is now available from yesterday on both the website of evad3rs but also in Cydia as a separate package for those who have already moved on to their jailbreak device.
With this new upgrade we have two major improvements:
Disable OTA update for iOS from Apple to avoid user error.
Fixed the Timezone / time problem encountered by several users.
GreekAppleNews went through this upgrade via Cydia and they all worked seamlessly with no problem affecting the kinds of existing tweaks whenever you go safely.
