If you are using the PanGu 7.1~7.1.x untethered jailbreak, PLEASE install this package!
This package attempts to cleanse your iOS install of all traces of the horribly-written Chinese AppSync, PPSync.
As of version 1.1-1, Complete PPSync Remover also cleans up after the version of PPSync that is included within the PanGu jailbreak.
Apparently, everything in PPSync is broken, including its prerm script which ... somehow fails for some people? What?
Running "removeppsync" as root from a terminal instance (like over SSH) will also execute Complete PPSync Remover, as well as simply installing the package.
