Yes, you can.
No, it comes with your iPod touch.
Every generation higher is better than its predecessor, so the 3rd generation is better than the second generation, but not by much. The 3rd generation only has a faster downloading or prosessing system then the 2nd generation but you can upgrade that for free or for about 5 dollars.
Yes they can. The new iPod Touches are simply cheaper and have a bigger and faster memory. They are the exact same design as the 2nd generation The new ipods are sure as hell not cheaper, but you can upgrade the downloading system for free on the 2nd generation and the 2nd generation willl be pretty much the same as the new ones. Unless you already have an advanced downloading system then you would have to pay like $10 or something but it saves you over $200.
You hold the on button and see if it needs to charge
Take the iPod Touch to USB cable that came with it, plug one end into your iPod and the other into the USB port on your computer. It must be on in order for it to charge.
There is no such thing as an iPod Touch 5th generation.
No, the 4th generation ipod touch has a camera on the front! xxx
Well, if you can't watch a movie on your iPod Touch, try re-downloading the movie from iTunes, delete the original movie on your iPod, and re-download it to your iPod and try watching it. It may have been a download malfunction.
