Three easy ways to clear out the junk on your phone

It used to be that you bought a new phone and got a fresh start. Now we just copy over all the junk from the old model onto the new one. Sure, it's faster and shinier, but it's packed with files you don't need, contacts you haven't talked to in years and photos you don't remember taking -- or want to see again. It doesn't take much effort to clear things out if you know what to do. You'll thank yourself (and me) later.
