So say you are an important guy in some respects and because of that, you have a lot of phone numbers and text messages on your phone.  Now say you get a new phone, which all of us seem to do about once a month these days.  Wouldn’t you make sure to clear out your old phone before getting rid of it?  Of course you would, because you aren’t from 1977, you know what a cell phone is, and you aren’t a moron…or at least a big enough one to think that someone might take a peak in your important by proxy phone!
