If your iPod home button is not working at all you can however add an alternative home button called assistive touch. This works with iOS 5 and up. Go to settings-general-accessibility-assistive touch on. A little white circle appears. If you tap it, it gives you 4 options. You can move it anywhere you want on your screen. My home button stopped working and that assistive touch feature saved my life! It's not as great as the home button though because it takes 2 taps to get to the home screen but it's better than nothing. It's a life saver!!
