Just to make sure that your Dad doesn't think that this is some sort of kid fad, I'm a 54-year old retired US Marine Corps Colonel.
if you have insurance on your phone the most you will have to spend for a new phone is $89. if you follow the steps exactly as stated your phone will more than likely be unharmed. and from personal experience if you root your phone and need to use the warranty a simple unroot will be good enough to get the phone passed through verizon. I needed a replacement phone so I unrooted, took the phone in and they switched it out with no problems.
