Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Or just register your phone with google (or apple). They can make it ring even if on silent. They also show you its location on a map and provide other functionality like the ability to lock it or wipe it. Google "where's my device" I have used this feature numerous times.
It's free but you owe me $20 if this tip ever saves your expensive phone - joking
That's what I wanted to hear. "Apple KNOWS where you are!"
Actually, my phone is a cheap Android and I turn off the location but thanks for the tip.
