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.

You can't, you should have synced them. You will have to purchase them again.

When it says reboot click reboot then it probably says plug into itunes so you plug it into your computer, open blackra1n and click make it rain and then you can do that and your ipod reboots and the guys picture goes away your ipod will be recognized by itunes and you wont loose all your apps.
To turn on a IPod that won't turn on you need to hold down the top button and the bottom (i think) to reboot (not restart) a IPod
You can reboot an i pod touch by pressing down the power button and the centre button for about until an apple sign comes up.
REBOOT, but DON'T just Respring
