I keep my phone on a lanyard all the time when I'm working, because I tend to misplace it otherwise. Most bumper cases have dual holes at one or both bottom corners that you can thread a carrier loop through, that then can loop through the lanyard clip. I recommend using a lanyard ribbon at least 1" wide; narrow cords can get uncomfortable with that much weight on them. (It's not really *heavy*, but it's enough to dig in to your neck a bit.)
