Use a loop of dental floss snapped between the phone and the case. The waxed stuff is incredibly tough. You only need it there when you're in a circumstance like orienteering.
Eagerly awaiting word of whether you found the phone in that little reentrant.
Facebook tells me that she found the phone!
So glad you found it! A friend lost her phone at an event. I lent her mine so she could use it to call her phone. She didn't have the benefit of GPS technology!
Amazing! You *are* MacGyver.
I was SO RELIEVED! I need to actually turn-on and configure the Avast Anti-Theft app I have on my phone; that would have given me lots more options.
