proven as bogus. no way that does anything.If those suggestions don't work, try the home button recalibration method.
1) Open a stock apple application. ie one that comes with a factory fresh iPhone (weather, stocks, calendar, safari, etc.)
2) Hold the power button until the slide to power off slider comes up.
3) Now hold the home button for a couple seconds until the slider goes away and the iPhone returns to the homescreen.
4) Enjoy your more responsive, working home button!
