|Start with an unwanted pair of headphones.|
|Remove the headphone jack from the cord - any auxiliary jack would also work.|
|Place the jack (ghetto silencer) into the headphone port on your cellphone.|
So, what I thought would be an easy way to silence a phone turned out to be a hoax. Sorry, kids. That being said, I did test this life hack on a rocking awesome iPhone 5 which is probably programmed to resist such little tricks. I may expand my test to the far inferior Android market to see if it works any better there.
