My phone just notified me that Kickback and Soundback were updated, what are they?
These are accessibility apps. One of Motorola's FAQ questions summarizes their purposes well:


  KickBack - Check to vibrate the phone briefly as feedback as you navigate the phone’s user interface, press buttons, and so on.
  
  TalkBack - Check to cause an installed speech synthesizer to speak the labels or names of items as you navigate the phone’s user interface.
  
  SoundBack - Check to play a sound as you navigate the phone’s user interface.
