For lock screen animation tweaks, I?ve always preferred Unlockize to Unfold (more animation options) and tonight the beta got an update I?ve been waiting on since iOS 6 came out (bringing back on/off toggles for the ?Slide to Unlock? arrow and slider background so themers can use their own if desired). If you owned it before you can find the updated beta by adding the getdelta.co repo to your sources. Seems like it may also be released as a regular build soon!
