You hold the home button and the lock button together for 10 seconds and it should give you a hard reboot.
The iPod touch must have a volume control. You can control the volume by either clicking the two buttons on the side of the iPod touch, or you can move the circle on your screen left to right to adjust the volume.If it doesn't have either of those two options, your iPod Touch is broken.
No, however the ipod touch 4g has two cameras on it
The ipod touch 4th generation has two cameras, a front facing camera and a normal camera.
Any iPod Touch 2G case WILL fit the 3G. I've purchased two myself.
You have two options: 1, get latest update - 5.1 this will get jailbreak off 2, set it back to its factory settings - go to Setting - General - Reset - Reset All Settings
On an iPod touch, only the newest model has a camera. If you're using an iPod 4th generation, just open your camera app to take real-world pictures. Using any other iPod touch, the only thing you can take is a screen shot. To do that, you simultaneously hold down the power and home buttons for a second or two, then let go (screen shots work on all iPod touch models, if I remember correctly)
No, currently the only ipod w/ a camera is the previous generation (4th?) of ipod nano and the 4th generation ipod touch, which contains two.
The iPod Video does not exist, but look on the bright side. The iPod Touch now has two cameras! A front and rear, much like the iPhone 4.
Depends on the iPod. The volume on any iPod with a click wheel can be changed by moving your finger in a circular motion on the wheel while playing a song. If you are using a touch screen iPod (or other Apple product), move the circle on the blue bar that appears on the screen while music is playing, or us the two buttons on the side of the iPod.
The iPod Touch 3G in incapable of taking pictures because it has no camera. If you really want to take pictures with your iPod i suggest upgrading to the iPod Touch 4G as it DOES have a camera built in. Two in fact.
When you get your iPod touch, it will include a pair of headphones, a quickstart guide, warranty details, a charging cable and two  stickers.
Yes, or you can use an iPod touch and an iPhone 4.
