Just a few hours ago came an update in Cydia Evasi0n for all users who had jailbroken . This update mainly solved two problems , failure to open the Weather application and issue preventing restart correctly. Now these updates are included in the official tools for those who have not yet done the jailbreak.
Evasi0n , tool for Windows , Mac and Linux that does the untethered jailbreak for iOS 6.0, 6.0.1, 6.0.2 and 6.1 , has been updated for the first time to prevent the occurrence of the two aforementioned errors , so if you had not jailbroken because you were waiting for pulieran failures and you can do it with confidence.
If you already had the jailbreak do not have to do it again or use the tool again , all it takes this tool has been updated via Cydia for those who already had it done , so you do not have to do anything except go to Cydia and install updates will appear .
If you have already installed the updates and you still have errors is because this update does not support AppSync , a modification to pirate applications. What you should do is uninstall AppSync , restart and re- use the tool Evasi0n your computer , you will lose all your installed tweaks , but it's the only way to fix the errors.
