iPhone headphones not working? potential fix here

If, like me, you suddenly discover that your iPhone isn't playing music through your headphones, even though you can hear when you disconnect it, you might try this: 1. Reboot your iPhone by pressing down on the top (power) button for 5 seconds, sliding the "Shutdown" button, then after it's off pressing down again to turn on. 2. Unplug and replug your headphones a few times. Seems that there's an occasion "mixup" internall y that sees that something's plugged in but doesn't believe it's headphones. Yeah... anyways. Worked for me. Was rather annoying.
