What’s the most important step you take to customize your phone? Maybe you go with a stylish case? Do you like to keep changing things up with a fresh wallpaper? Or are you the kind of enthusiast who just renovates down to the studs and installs a fully custom ROM?

It wasn’t that long ago (at least, what’s a couple decades between friends?) when there was no higher form of phone personalization than the custom ringtone. Over the course of a few short years we went from simple blips and bloops, to polyphonic recreations that were at least recognizable as actual songs, to straight-up MP3 ringtones. And after scaling that mountain… we all sort of just moved on?
