Is anyone else just getting scripted lame answers from the genius bar?  I went in with a home button issue on my 4.  "It must be because you have apps running and it uses up processing power.  Close all your apps."  A friend went in with 4s that had no audio on outgoing calls.  "Apps use processing power, so you should close them all when you make a call."  SERIOUSLY!?!?!?!?
