Some people getting this problem after install appsync, and also me. Some stock app like safari, mail, calculator and weather app crash.
I think it because we install appsync after install cydia tweaks.
Here simple step how to fix it, and it work for some users, but not work for me. I use fix 2.
Fix 1 :
1. Open cydia and remove or uninstall appsync. If you have afc2add install, uninstall it too.
And do reboot.
2. Locate to var/mobile/Library/cache/, remove this 2 file :
3. And do reboot again. Dont respring, because it will not work. After reboot if u find all install app gone, dont worry. It will back again.
And try and make sure some stock app now will work or still crash. If still crash, try this :
Fix 2 :
