不小心用到盜版，算是無心之過啦。
作者在cydia的軟體FAQ裡頭，寫了一大串說明，轉貼給你參考。
Piracy Hurts?
FolderEnhancer is not free software, and there is no 'trial' version. If you have FolderEnhancer installed but have not paid for it, you are pirating it.

A lot of time and effort has gone into and continues to go into the development and support of FolderEnhancer. Yet this software has been pirated by several tens of thousands of people, and more than half of the support requests received are from pirates. Yes, that hurts. =(

The "Piracy Hurts" message is a part of FolderEnhancer's anti-piracy measures. After you receive this message, your device will be placed into MobileSubstrate's "Safe Mode" where you can safely uninstall the pirated package via Cydia and, if you choose to, purchase the official package from the Cydia Store. Remember, "Safe Mode" only disables extensions (such as FolderEnhancer), not apps (such as Cydia).
