On several occassions, I've heard my iPhone 4S - while locked and set down flat -- make a sound that is similar to coins rattling or a piece of glass breaking. I checked all my alert sounds and no sound like that is even an option. When I pick up the phone and unlock it after, everything is fine and there's no message displaying. Any ideas or info on this?
iPhone 4S, iOS 5.1.1
I actually just had another instance and continue to try to figure out what it is.
Since it's a noise and a vibrate (mine does both too), I'm focused on it being a notification of some sort, so I looked to see what Apps had any notifications when it happened. I saw one prime suspect - Bejewel Blitz. I checked my noticiations setting for Blitz and badges and sounds were turned on. I turned off the sounds. I hope that's it; too early to tell, though. Do you also have BeJeweled Blitz on your phone?

This just happened to me as well. The noise was accompanied with a vibrate, but when I unlocked my phone there was no new mail, and nothing else appeared to be wrong.
What does this mean?
iPhone random coin, breaking-glass noise sound
