New day, new tweak in Cydia: FolderLock. With FolderLock , you’ll be able to use the same principle with folders as well. Settings for FolderLock are located in the Settings.app under its name FolderLock. The settings are pretty simple with an Enable/Disable switch and Insert password. A Protect Options section has some toggles for protecting the Settings.app, Spotlight, and Multitasking.
NOTE: Don’t put the Settings.app or Cydia.app inside a folder. If you forget your password and can’t access both of these applications, then it makes things much more difficult. If this does happen however, you can remove FolderLock via SSH (/Library/MobileSubstrate/DynamicLibraries). SBSettings allows you to disable it also.
FolderLock is available for $1.59 in Cydia Store via BigBoss repo…
