How can I find my muted iPhone in my house!?  I know it's here somewhere!

This is something I frequently need to do.  I have my phone on mute after an appointment, and then put it down somewhere and can't find it!  No point calling it - because its muted, so won't ring!

So what can you do when this happens?  How can you use another iPad or iPhone (even someone else's) to find your misplaced iPhone or iPad?  And what do you do if you haven't got another iPad or iPhone?  Is there some other way to find the missing device?

Yes the is.  Find out how in this Handy Hint.
