Help - 3GS seems to be stuck on mute!

[Whackintosh]

Not sure how this happened, but my 3GS is now completely silent (ringer, keyboard clicks, everything) in spite of the volume being up to its max. Is there a hidden mute feature somewhere that can be the culprit? Any tips would be greatly appreciated!

Reboot the phone? Hard reboot? *hold down lock and home buttons until phone turns off*

Do you use headphones? Sometimes the digital headphone jack thinks you have them plugged in when you haven't.

Test this a bit. Maybe plug in/unplug a bit to see if this changes anything.
