Home Button Stuck Down on iPod Touch 4G

[crunc]

Reset the home button? That seems like a weird concept and a tad hard to believe, but I found a video on youtube and tried it. Verdict is out, but I'll see how it goes over time.

EDIT: it might have worked? How? I don't get it. Also sometimes I think the home button is working right, then later it starts being flakey again, so this could all be coincidence.
