I've not been able to figure out why my iPhone periodically emits a vibration/sound. There is never any sort of information message or icon or anything associated with it. I'd love to know what function it serves.

Either to tell you the battery is low, or that someone wants to talk to you. Or just to remind you that you are the proud owner of a really annoying device.

Not power or messages... do other people's phones do this?

[syhprum]

PC,s do this too maybe its just a schizophrenia inducing pulse of microwaves that's missed its proper target

Maybe it's a mechanism for phones to talk to each other... check to see who's in the vicinity.

Mobile phones may beep randomly due to an interrupted microwave signal.
