How do you chrage and iPod Do you need to buy the connection to charge it?

First, you can use your computer to charge it. Or, if you want a wall charger, you need a AC/DC adapter that has a female USB socket and outputs 5V DC with at least 500mA (lower amperage will work; it will just take forever). You probably won't find one that is cheaper than the Apple one in most stores (there's a Sony one that they sell at a lot of places, but it's only about $5 cheaper). You can try buying one on eBay or Craigslist. Or, if you're really daring, you can try charging it with an onion and electrolytes: YouTube.com/watch?v=GfPJeDssBOM">http://www.YouTube.com/watch?v=GfPJeDssBOM (neither tested nor recommended by me).
