How do you download games onto the itouch?

Its Simple!!!
Al you gotta do is connect your iPod to the internet through the settings menu (type it into YouTube some friendly guy/gal will tell you how) then launch the app store from your home screen and download apps some are free but the ones you pay for you have 2 options:
1:get a app store giftcard
2:pay through credit card
then launch your app from the homescreen updates come out regularly so keep an eye out
