Did your home button got broken? I would suggest jailbreaking your iPod (assuming its still kind of working if you fiddle with it) and than install "activator" then you will be able to control your iPod without touching the Home button or Sleep button.
Settings>general>accessibility > assisting touch on> than a white dot with come up click it and then a home button on screen will come up
my home button is broken to but if i to close an app i use the asistive touch witch lets you use the home button just by going on to it and tapping home you turn it on in settings-general-accessibility- and turn the assistive touch on then a dot will appare on your screen tap it press device then rotate screen and you done
Double click the home screen button, touch and hold the app you want to close, a red minus sign will appear in the icon, just touch it.
The home button
If you keep your fingers on the home button and the lock button at the same time for 10 seconds, your iPod shout reset.
It's called the home button, and it is the only button on the screen of the ipod touch. It is circular with a white square. it takes you back to a home screen.
the "home" button
Try clicking the home button
That would depend on which iPod you're talking about. I have a iPod Touch. To close it, just continuously press the On/Off button on the top left of the iPod. To force close it, hold both the home screen button (located at the bottom middle of the iPod) and the On/Off button at the same time for about 10 seconds.
Press the home button and power button at the same time
Then it's time for a new iPod.
no the ipod touch only has the one "home" button
You press the home button and sleep button at the same time and keep holding them until your iPod touch reboots.
